Causes Of Teeth Sensitivity
Why Are My Teeth Sensitive?
Teeth can become sensitive when the enamel gets thinner, it can leave the inner layer of dentin exposed. It is the dentin that protects the internal pulp and nerve of the tooth. This can also happen if the gums recede.
The pain is felt when the nerves are exposed to heat or cold, this is mainly when we eat or drink although exposure to cold winds have also been known to bring on tooth pain Small holes can develop in the enamel which allow the heat (or cold) to travel down to the nerve in the tooth.
The majority of toothpastes use fine abrasive materials to clean the teeth, baking soda, silica, aluminium oxide and calcium carbonate are a few of the usual ingredients, Both whitening and anti tartar toothpastes are known to cause some cases of teeth sensitivity.
So What Can I Do About My Sensitive Teeth
First of all look at both your toothpaste and your brush, try a de-sensitizing toothpaste as these can be effective, look at your brush, do the bristles spread sideways ant point outwards? If they do, you are most certainly pushing too hard, this can not only harm the enamel, but can also damage the gums as well.
Try and use a brush with medium to soft bristles, and be gentle, use light but firm brushing motions without pushing into the teeth and gums too hard.
If Changing your toothpaste doesn’t help, then look at the types of foods you eat and drink, both foods and drinks high in acids (such as fruit juices) can harm the teeth reduce the intake of these and also try and rinse mouth with water after eating or drinking.
The use of some teeth whitening toothpastes and kits can also cause sensitivity, this is where the whitening gel gets through the small holes in the enamel and irritates the nerve.
When using teeth whitening kits, it is also a wise move to use Remineralising gels along side the treatment, these are supplied by most reputable teeth whitening companies and work to replenish the minerals and enamel of the teeth, reducing the risk of sensitivity. Basically they seal or plug the holes that lead to the nerve.
Serious Tooth Sensitivity could well be the sign of other more serious dental problems such as serious decay or even an absyss, in these cases always check things out with your Dentist
Maintaining good dental hygiene is important; also a minimum of two visits per year to your dentist and regular brushing and flossing should be maintained.
