What Causes Tooth Sensitivity

Just Why Are My Teeth Sensitive

Sensitive Teeth occurs when the enamel of the teeth gets thinner, it can leave the dentin (which protects the internal sensitive teethpulp of the tooth) exposed. This can also occur if the sufferers gums have receded. Pain or discomfort is felt when the nerves within the dentin are subjected to heat or cold, often food or drinks, but it can also me caused by exposure to cold air or contacting hard objects.

The tooths enamel can also develop small holes as we eat hard, or very hot or cold foods. these holes, although usually really tiny can allow the heat and cold to get through the enamel and travel through to the nerves.

Most toothpastes use fine abrasives to clean surface of the teeth, these include, baking soda, calcium carbonate, silica and aluminim oxide. Both Anti-Tartar and Whitening toothpastes are known to be regular causes of tooth sensitivity.

If you do suffer from sensitivity, there things that can be done, de-sensitising toothpastes or those that have a mild formula are usually quite effective.
Another cause can be agressive brushing and the hardness of the brush itself, while we may think that a hard brush will clean better, what we are actually doing is damaging the protective enamel and possibly the gums themselves.

Check Your Toothbrush

Try and use soft tooth brushes with gentle strokes – Be light but firm.

Naturally, serious sensitivity can be a sign of other dental problems such as serious decay or absyss, these should always be checked out by your dental surgeon.
