Tooth sensitivity happens when hot, cold, sweet or very acidic foods or drinks are consumed. Sometimes breathing or sucking in air can cause this unpleasant sensation too.
How to manage tooth sensitivity
1 Check with the dentist to treat any disease in the mouth such as decay and gum problems.
2 Correct brushing technique to reduce further damage to gums and exposure of roots
3 Use toothpaste for sensitive teeth.
Causes of tooth sensitivity
1 Enamel and tooth wear that is due to;
Aggressive brushing technique wearing teeth surfaces
Teeth grinding result in wear and exposure of underlying dentine
Gum disease with pockets exposing roots that have nerve supplies
Acid erosion from acidic foods and acidic mouthwashes resulting in erosion of enamel
High sugar foods and drinks
Chipped or fractured teeth
Decay or leaky fillings
Recent dental procedures( usually temporary)
2 Gum recession due to;
Vigorous and wrong brushing technique that causes gums to recede and roots to wear— abrasion cavities
Gum disease where there is pocketing and bone loss where roots are exposed
Ingredients in toothpaste that are used to reduce sensitivity of teeth
1 Pro-argin formula
2 Cal-seal technology further fortified pro-argin protective layer.
