An air pollutant is a substance in the air that can have adverse effects on humans and the ecosystem. The substance can be solid particles, liquid droplets, or gases. A pollutant can be of natural origin or man-made. Pollutants are classified as primary or secondary.
How is gum graft surgery performed? During gum grafting surgery, a periodontist will commonly take connective tissue from the roof of the mouth (palate) and suture it to the affected gumline. This allows more tissue to grow and close the exposed root surface (gum recession).
The key is how much bone is around the teeth. Gum tissue can be grafted to cover the recession. A periodontist could tell you your best options. If you do need implants, $4000 to $5000 per implant is a rough guideline, but you might be able to replace two lower front teeth with one implant.
