Tooth sensitivity is also known as hypersensitivity. It is a common dental problem that implicates twinge or discomfort in teeth on every occasion certain substances or temperatures are encountered. Having sensitive teeth can mean anything from getting a mild pang to having severe discomfort that can prolong for several hours. It can also be an early warning sign of more serious dental problems.


It has been estimated that approximately half population experience tooth sensitivity. It is more common in people aged between 20 and 40, although it can affect people in their early teens and when they are over 70.


The sensitivity of teeth happens when the enamel (which is the hardest substance in the body)of tooth is spoilt. Dentin is the material underneath and it contains thousands of channels. These channels lope from the surface to the nerve centre of the tooth through dentin. The channels enclose fluid and when something hot or cold is eaten the fluid moves and aggravates the nerve endings in the tooth which causes tenderness and discomposure.





  1. • BRUSHING TOO HARD: Brushing from side to side can cause enamel to be worn away mainly where the teeth meet the gums. The newly exposed dentine may then become sensitive.
  2. • DENTAL EROSION: This is loss of tooth enamel caused by attacks of acid from acidic food and drinks. If enamel is tattered away, underneath is exposed which may show the way to sensitivity.
  3. • RECEDING GUMS: gums may naturally recede and the roots of the teeth will become uncovered and can be more sensitive.
  4. • GUM DISEASE: a put up of plaque or tartar can cause the gum to recede down the tooth and even demolish the bony support of the tooth.
  5. • TOOTH GRINDING: this is a habit which involves clenching and grinding the teeth jointly. This can cause the enamel of the teeth to b worn away, making the teeth sensitive.
  6. • CRACKED TOOTH OR FILLING: A cracked tooth is one that has become broken.
  7. • TOOTH BEACHING OR TEETH WHITENING: some patients have sensitivity for short time during bleaching or afterwards.
  8. • AGING: with age teeth are worn away and the muscles become feeble. Teeth enamel thins and cracks with age making teeth more sensitive.
  9. • WEAR AND TEAR: ceratin activities smash up the tooth surface. This happens with the abrasive brushing, improper flossing, biting hard objects and chewing tobacco.wear and tear start from the cutting edge of the tooth with time the wear and tear increases and makes underlying dentin exposed.
  10. • SUGARY DIET: sugar gives rise to the bacterial growth which is to blame for the gums erosion and exposes the dentin causing sensitivity.
  11. • ACIDIC FOOD: acidic food like citrus fruits, tomatoes, sour cream, yougurt, aged cheese and acidic drinks like orange juice, wine.their continuous use makes situation worse and increases sensitivity of the tooth.
  12. • PAST DENTAL PROCEDURE: A dental procedure includes fillings and repairs, root canal, crown and teeth whitening. It is normal to experience sensitivity after a dental procedure ,but if the problem continues for a lengthy time ,it can be a signal of some infection.


MAINTAIN AHEALTHY ORAL ENVIRONMENT: brushing should be the key of the day and lock of the night.

  1. • It is better if you use a fluoridated tooth paste
  2. • Try with sensitive tooth paste
  3. • Change brush every 2 to 3 months
  4. • Evade brushing straight after eating because some food and drinks tend to soften the enamel of the teeth, so gap of one hour is sensible between eating and brushing
  5. • Clean other areas of mouth like tongue, inner cheeks and mouth roof
  6. • Rinse mouth every time after eating
  7. • Avoid eating sweets before going to bed.
  8. • Floss between the teeth once in a day
  9. • Rinse the mouth with anti-bacterial mouth.


After realizing you have tooth sensitivity, and then is what you can do about it. Visit your dentist, dentist undergoes through number of steps and test for sensitivity

  1. • Test for sensitive tooth-check if tooth is still vital
  2. • Cold test-cold dental material is applied to check if tooth needs a root canal or filling.
  3. • Heat test-hot dental material to check if tooth needs a root canal.
  4. • Looking for cavities in your mouth
  5. • Check if the teeth re mobile
  6. • Check the structure around the teeth
  7. • Biting on cotton or gauge-to diagnose the cracked tooth
  8. • Taking x-rays-to inspect hidden areas of the teeth, the bone &cavities


• Desensitizing toothpaste aid persons with the sensitivity problem. The main component of this toothpaste is strontium chloride and potassium nitrate. These two compounds wedge the transmission of pain signals from the surface of your tooth to the inner nerves by filling the bare tiny tunnels in the teeth, which are linked to the nerve.

  1. • Fluoride Application

    Fluoride helps avert the tooth decay by mounting the fighting capability of the tooth so that it can resist to acid attacks from plaque bacteria and sugars in the mouth. Fluoride is applied at the sensitive areas of the teeth. Fluoride reinforces tooth enamel and reduces the pain. A dentist can apply fluoride to the teeth as a gel, foam, or varnish.
  2. • Dental Bonding

  3. Dental bonding or tooth bonding is the process in which a tooth-coloured composite resin (plastic) is applied to the tooth:
  4. • To repair a decayed, broken and discoloured tooth
  5. • To make teeth appear longer
  6. • As a cosmetic substitute to fillings
  7. • To close spaces between teeth
  8. • To change the shape or colour of teeth
  9. • To treat the exposed root surfaces
  10. • Surgical Gum Graft
  11. • Gum grafts are used to cover the exposed roots. A gum tissue is taken from the palate or another cause in the mouth and attached to the affected tooth root. This can be done for one tooth, several teeth or even gum line.
  12. • It reduces tooth sensitivity as the uncovered roots are covered and cannot be affected to the temperature changes.
  13. • ROOT CANAL

  14. If rigorous pain is experienced besides with sensitivity problem and other treatments are not effective enough to solve the issue, the dentist may suggest root canal treatment. A root canal is a type of treatment to fix and save a poorly injured or contaminated tooth. The process starts by eliminating the damaged area of the tooth (the pulp), followed by cleaning and disinfecting it and then filling and sealing it. The pulp is damaged by a cracked tooth, a deep cavity and frequent dental treatment to the tooth. Root canal treatment is done in four steps which are:
  15. X-ray:X-ray of the mouth is taken to locate the possible tooth decay. Further treatment is based on the X-ray as it gives a clear idea about the correct location of the decay.
  16. Anaesthesia:The patient is given a local anaesthesia at the affected tooth.
  17. Pulpectomy:It involves elimination of the diseased tooth pulp, cleaning and disinfecting the affected part.
  18. Filling:After cleaning, the roots are filled with gutta-percha material and sealed with the cement.
  19. A root canal is considered as the most flourishing technique for eradicating tooth sensitivity.
  20. • Making a Mouth Guard

  21. One of the major causes of tooth sensitivity is bruxism. It is the grinding of teeth while sleeping. For such state, dentists advise a mouth guard to be worn during the night. The mouth guard is a appliance for the mouth that wrap the gums and the teeth. Mouth guard diminish the pain cause by sensitive teeth as it stops the grinding of teeth.

  23. Brushing technique is very essential. It is the fundamental step of attaining a healthy oral hygiene. Right technique can avoid a lot of oral troubles and can treat many others. Since abrasive brushing is one of the causes of tooth sensitivity, improving brushing technique is important to certify the health of teeth.
  24. Some brushing tips are given below:

  25. • Brush delicately, and two times a day at least.
  26. • Buy a new, soft-bristled toothbrush after three to four months of using it.
  27. • Clean your teeth every time you eat. Cleaning may include gentle brushing, flossing or simply swishing water around in the mouth for a few seconds.
  28. • Place your toothbrush bristles at a 45-degree angle to the gum line.
  29. • Brush every part together with all inner and outer tooth surfaces, using short and circular strokes.
  30. • Brush your tongue, as oral bacteria are found at the end of the tooth as well.

  32. Smoking boosts the danger of mouth pain, cavities and gum slump. Evading it can lessen the probability of these conditions and thus it can be supportive in treating tooth sensitivity

Wisdom teeth removal

Wisdom teeth is the normally used expression for “third molars”-the large teeth right at the backside of the oral cavity that come through end, usually in between the ages of 17 and 25, while they can also erupt more afterward or not at all.


Long ago in 17th century,these teeth were known the “teeth of wisdom”as they emerge when you were no longer a child and supposedly wiser. In the 19th century, the term ‘teeth of wisdom’ changed into ‘wisdom teeth’.

How many wisdom teeth does a person have

Populace generally have four: upper left, upper right, lower left, and lower right.
If they are lacking, the reason is the genetic frame. It's been predictable that about 25% of people are lacking one or more.

Impacted wisdom teeth

An "impacted" tooth is refered to one that is not fully erupted (appear into its likely position).
This failure to erupt correctly might be because:

  1. • There is not sufficient room in the individuals mouth to put up the tooth.
  2. • The tooth's eruption path is hindered by other teeth.
  3. • the angulations of the tooth is out of place.

Types of impactions

  1. • Mesial
  2. • Vertical
  3. • Horizontal
  4. • Distal

These provisos are used to demote to the general angulations (positioning) of the tooth.
The term "Mesial" (also mesio-angular) represent that the tooth is angled forwards, toward the front of the mouth. This is the most regular type of wisdom tooth impaction.
The other types of impactions, in are the vertical, horizontal, and distal types.

impactions have a somewhat normal direction.

Horizontal (also traverse) impactions have an placement where the tooth is lie down on its side.

A Distal (also disto-angular) impaction has an angulation that is normally directed in the path of the rear of the mouth

Other Types of Impaction

Full-Bony Impacted:

This form of wisdom tooth removal is the most complicated for the basis that the wisdom tooth is wholly wedged in the jowl

Partial-Bony Impacted
In this case, wisdom tooth removal entails hauling out a tooth that is to a degree trapped in the jawbone.

Soft-Tissue Impacted:
This type of wisdom tooth removal is not as much of complicated for the reason that the tooth is solely trapped under the gum.

This type of wisdom tooth removal is the simplest as the tooth has already emerged in the mout

How likely is it that your wisdom teeth will be impacted?

Studies put forward that the rate of having at least one that's impacted is in order of 65 to 72%. Lower wisdom teeth are more liable to be impacted than upper ones.

What causes wisdom tooth impaction?

The grounds why some wisdom teeth are impacted is not an easy query to answer. A chief reason merely appear to be a situation of insufficient jawbone space behind a person's second molar.
Why this short of of space exists is not fully recognized. There, however, seem to be a connection between large tooth mass and/or the occurrence of widespread tooth crowding and having impacted wisdom teeth.

The human diet has changed.

The dietary variations take on by present man have been hypothesize as playing a part in the occurrence of 3rd molar impaction.
The coarse character of stone-age man's diet had the outcome of creating wide tooth wear When this type of wear takes place, it tends to lessen the "length" of the teeth (as a set), thus producing extra jawbone space to house the wisdom teeth by the time they blow up. In evaluation, the diet of modern man does not typically origin a major quantity of this type of wear.

When Should I Have My Wisdom Teeth Removed?

It is not judicious to linger until your wisdom teeth begin to bother you. Earlier taking away of wisdom teeth results in a less problematical healing process. It is sturdily suggested that wisdom teeth be removed by the time the patient is a juvenile adult in order to avert upcoming trouble and to make sure most favourable healing.The researchers found that elder patients may be at bigger danger for disease, including periodontitis, in the tissues adjoining the third molars and closest teeth.

Reasons to extract

  • • Pericoronitis / Infection.
  • • obscurity related with tooth decay.
  • • gum disease
  • • Pathology - Cysts, tumors.
  • • Risk of damage to next teeth / Root resorption.
  • • unmitigated pain, headaches, pressure.
  • • difficulty allied with deprived tooth alignment
  • • Wisdom teeth initiate front teeth crowding.
  • • The "every third molar must go"in sequence.

What is pericoronitis?

"Pericoronitis" refers to a bacterial infection to be found in the soft tissues that envelop the crown part of a incompletely emerged tooth.

Wisdom teeth and Tooth decay

several wisdom teeth have to to be extracted due to problems allied to tooth decay.

1) Cavities and wisdom teeth.

Decay can occur on any tooth facade where dental plaque is permitted to stay for extensive periods of time.
It means, if the spot of a wisdom tooth is such that its hard to cleanse , it will be at heighten menace for cavity formation.

a) Some cavities in third molars can be restored by inserting a dental filling.

it's achievable that the wisdom tooth can be repaired by method of placing a filling, same as any other tooth. This can be specially true in those cases where:

  • The decay is quite small.
  • The cavity is present on a fraction of the tooth that's promptly handy
b) at times pulling the tooth is a healthier solution.

In a number of conditions, the dentist may consider that pulling out the tooth makes a healthier option than repairing it.
Repair may not be possible. In a few cases, the rot may be located in such an awkward location that the dentist notice their right of entry to it is very limited, if not unfeasible.

2) A wisdom tooth may set neighbouring teeth at risk for cavities.

o The gap between this wisdom tooth and neighbouring tooth can't be clean.

Third molars that don't come up to wholly into usual position often wrap up generating a catch for dental plaque and debris inbetween it and the adjacent tooth forward, the 2nd molar. If the gathering that builds up in this ambush can't be sanitized out carefully, the wisdom tooth be located at much greater danger for budding a cavity and also the 2nd molar.


Wisdom teeth can be tough to clean. And in such cases, they are at more risk of budding periodontal problems (gum disease).
, this is an main issue for the reason that the gum health of our 3rd molars doesn't only have an effect on them alone but probably other teeth in your mouth as well. for this grounds, the removal of your wisdom teeth may be a needed preventive measure.

Why can wisdom teeth be at increased risk for developing periodontal problems?

Gum disease is caused by oral bacteria. And at any time a tooth cannot be scrubbed appropriately on a normal basis, the bacterial-laden film) that amasses around it may lead to its formation.
The place of several wisdom teeth can be such that it formulate them very difficult to clean.
And when this kind of additional defy subsists, the teeth concerned are left at even larger threat for budding periodontal problems.
superfluous causes to remove wisdom teeth.
- twinge, heaviness, headaches, cysts, tumors, soft tissue trauma, 2nd molar root resorption.

  • Cyst or tumour for persistent pain / Heaviness / Headache.
  • deprived tooth arrangement or location
  • Damage caused to adjoining teeth..

Rationale to extract third molars -

A) Wisdom teeth that trigger pain.

  • The most familiar cause why populace look for an assessment of their wisdom teeth is for the reason that they've recently experienced a throbbing incident.
  • Having tenderness is the most regular third molar symptom. 33% of patients who encounter problems state having it.
    • a) The tooth's eruption procedure.
      It's doable that the discomposure a individual observes with a wisdom tooth is related with the route of it coming in (its "eruption"). If so, what's encountered may either be sporadic or of continuous period.
    • b) Additional causes..
      pain related with an infection in the region of the tooth, or twinge to the lean layer of covering that wraps it. Non-odontogenic conditions.

      imprecise symptoms concerning ache, stress feeling or annoyance are at last recognized to non-tooth circumstances.One is tempromandibular joint (jaw joint, TMJ) dysfunction if the individual has a addiction of scrunching or milling their teeth..

B) defectively located wisdom teeth.

  • a few wisdom teeth manage to break out but on the other hand have a positioning that triggers, or can bring about, tribulations.
  • Teeth which are sturdy to clean. Some wisdom teeth dwell in a place that make them very difficult to brush and floss. In that case, both they and their adjoining tooth are to be found at bigger risk for snags with tooth decay and gum disease. And for that reason, they need to be get rid of prior to problems develop.

C) Cysts and tumors.

they're not an mainly general occurrence, cysts and tumors can build up in the tissues in the region of an impacted wisdom teeth.
If pathology is observed , the connected tooth have to be aparted and its cyst or tumor assessed by a pathologist.

  • A) Do all wisdom teeth need to be removed? No, without question a viewpoint that a tooth, just because it's a wisdom tooth, must be extracted is not justifiable.
  • Do impacted wisdom teeth call for to be extracted? It may come as a revelation to you but no, not all impacted wisdom teeth essentially must to be aloofed.
    Clearly, problematical teeth must be pulled out.
    One of the chief aspects that a dentist will take into thought when assessing an impacted wisdom tooth is its impaction type.

D) The patient's age ought to be factored in.

When bringing about a conclusion regarding an impacted wisdom tooth, it's imperative to think about the patient's age. Young patients tend to practice fewer problems with third molar surgery than elder adults.

E) Any retained wisdom teeth ought be keep an eye on often.

wisdom tooth's position may vary. This comprises equally the development of pathology (cysts, tumours, decay)

X-ray appraisal will be obligatory.

So to observe for variations a dentist will usually suggest that the teeth in question have to be cyclically re-evaluated. These inspections will about definitely call for to take in the use of dental x-rays

difficulties and risk have got to be considered.

  • 1) All surgery entail risk.
    It's main to keep in mind that all kinds of surgery, plus oral surgery, have some inbuilt risk
    For this cause, wisdom teeth have to barely be taken out in cases where a practical case for their elimination can be ended.
  • 2) The patient's health status must be considered.
    The condition of a individuals wellbeing may contraindicate having an extraction. consideration consist of primary systemic disease and issues that may set hurdles or obstruct with the curative process .

Wisdom Teeth Symptoms

  • Bed breath/Taste
  • Around the wisdom tooth
  • Pain/Difficulty opening mouth
  • Ear-ache
  • Swollen glands

How are impacted wisdom teeth treated?

If you’re impacted wisdom teeth trigger signs or dental problems, your dentist may recommend pulling them out.
Surgery to get rid of wisdom teeth is as a rule an outpatient practice. You can depart to home the same day. A dentist or oral surgeon carry out the procedure, which is well-known as wisdom tooth extraction.
your doctor may use anesthetic drugs to persuade a type of anesthesia, such as:

  • • local anesthesia to numb your mouth
  • • sedation anesthesia to calm down you and block pain
  • • general anesthesia to make you sleep and not f eel anything during the procedure throughout the course of action, the surgeon will make a cut in patients gums and take out problematical bone prior to taking away the tooth. They’ll close down the cut with stitches and pack the gap with gauze.
    The full surgery commonly expends about 30 to 60 minutes.
    If your teeth are wholly impacted and hidden low inside your gums or jawbone, it may be tough for your surgeon to eradicate them than if they’ve broken down through the gum.

Recuperating from wisdom tooth extraction

Most persons can get back to their regular activities some days after surgery. It takes around six weeks for your mouth to fully heal.
You most likely won’t be able to open your mouth generally for around a week, so need to take soft foods.
following surgery, you may encounter some ache, bleeding, and inflammation. Your consultant will give you detailed directions for controlling discomposure for example having pain medications and applying cold pack together.
Even though intermittently, you may build up a excruciating dry socket. This occur when the blood clot that’s supposed to develop after surgery doesn’t form correctly or happen to dislodged from the socket and exposes bone.
Some examinations have recommended that holding impacted wisdom teeth may lead to more ache and other troubles after surgery.
