Tooth Decay may or may not cause discomfort, even though it doesn't hurt, the tooth is deteriorating.
Using higher magnification and powerful lighting, it is easier to detect decay at an early stage to prevent excessive tooth damage. When cavities are small, they are much easier and less expensive to treat.
Early tooth decay does not tend to show many physical signs. Sometimes the tooth looks healthy, but your dentist will be able to see from an x-ray whether you have any decay under the enamel, any possible infections in the roots, or any bone loss around the tooth.
Screening for gum disease should form an integral part of your routine examination. Gum disease describes swelling, soreness or infection of the tissues supporting the teeth. There are two main forms of gum disease: gingivitis and periodontal disease.
Gingivitis means inflammation of the gums. This is when the gums around the teeth become very red and swollen. Often the swollen gums bleed when they are brushed during cleaning.
Long-standing gingivitis can turn into periodontal disease. There are a number of types of periodontal disease and they all affect the tissues supporting the teeth. As the disease gets worse the bone anchoring the teeth in the jaw is lost, making the teeth loose. If this is not treated, the teeth may eventually fall out.
