Your crown of tooth is generally covered with enamel, a hard protective layer that protects the tooth nerve. If your teeth are sensitive it is likely due to eroded enamel, or gingival recession that has exposed the root of the tooth and the nerve to the elements. Any teeth can be affected but the most likely are those at the front corners of the mouth. It is suggested that this might be because these are the teeth which tend to be brushed more vigorously causing the wearing away of protective tooth enamel. Reasons for sensitivity and dental pain are:
Biting abnormalities to abnormal tooth grinding.
Toothbrush abrasion i.e. the wearing-away of enamel and/or recession of gums caused by over-enthusiastic or incorrect brushing.
Dietary erosion - the destruction of enamel by acidic food and drink or by acid regurgitation from the stomach.
Habit - nail biting or the placing of metal objects between the teeth.
Attrition - the wearing away of enamel by tooth grinding.
Chronic gum (periodontal) disease
Surgery (difficult tooth extractions)
Incorrect tooth brushing
Sensitivity and dental pain can also be experienced for a number of other reasons:
Chipped teeth
Fractured or cracked fillings
Dental decay (caries)
Deep fillings
Cracked teeth
What can I do about sensitive teeth?
There are many brands of toothpaste that claim to reduce sensitivity. This should be your first choice for treatment. Try a brand for 2-3 weeks (use 2 x day). Don't rinse with water after brushing. If sensitivity remains, try a different brand. When you find one that works for you, then continue with that specific brand. Also, don't brush right away after eating, instead rinse with water and then brush 30 minutes later. The acids in our mouths are at their highest 20-30 minutes after eating so this is when the tooth enamel and root surface is most vulnerable.
Analyze your diet and reduce intake of sugars and acidic foods and especially soda pop (including diet soda) or fruit juices. Salad dressings are very acidic - consider having it "on the side" with your salad. Also be aware that anything labelled as "sour" is very acidic.
How can I avoid sensitivity?
You should avoid the use of whitening and tartar control toothpastes. These toothpastes contain ingredients that may increase the risk of developing sensitivity. You should also avoid use of hard or medium bristled toothbrush and be careful not to brush your teeth too vigorously. This can wear down the enamel or root surface and expose sensitive spots.
Eat cheese at the end of your meal. The potassium, calcium, and magnesium will linger in your saliva and provide further remineralizing of your enamel.
At Finesse, we can help by:
Applying fluoride varnish to exposed sensitive dentine or cementum to block the tiny tubes which are exposed.
Reviewing your homecare techniques, products, etc.
