It is important to remember that there is a wide range of normal variability in the 12 lead ECG. The following normal ECG characteristics, therefore, are not absolute. It takes considerable ECG reading experience to discover all the normal variants.
Check-Ups. Common check-up and cleaning costs vary. Dentists charge different rates depending upon your situation and where you live. In most places, an average check-up costs about $288, which covers an exam, x-rays and cleaning.
Costs: Laser whitening will run around $1,000; a bleaching application in a dentist's office costs about $500. If the dentist does an initial bleaching and then sends you home with a kit to use, expect to pay around $300. The costs of over-the-counter whitening kits can vary widely â from $30 to $300. Don't be snookered into the more expensive products, says Wolff.
