Best dental clinic in 200 feet radial road - Amethyst Dental & Aesthetics. Dental Implants: Gaps’ usually refers to the space left by missing teeth, although sometimes they may be due to natural spacing between the teeth. Teeth may be missing because they have been removed due to disease [e.g. dental decay (caries) or gum disease (periodontal disease), or because they have failed to develop (hypodontia). This failure for a tooth or teeth to grow is relatively common affecting 3-8 percent of the population. Although it is not always necessary to replace missing teeth it is often done for appearance reasons or because of problems with speech or eating. There are a number of ways to replace teeth and these include dentures, bridges, and implants. Contact us Amethyst Dental & Aesthetics from Kovilambakkam.
