It is estimated that more than half of Canadian adults have sensitive teeth due to recession of the gums. This occurs when the dentin becomes exposed as the protective cementum layer on the roots is lost. This dentin has little tubules which contain fluid. Its is believed that rapid movement of this fluid within the tubules (caused by heat, cold, air and pressure) causes sensitivity which can elicit a sharp pain.
There are various methods of teating root surface sensitivity including fluoride varnishes and potassium nitrate (Sensodyne). Colgate has recently introduced a product called Sensitive Pro-Relief. Perhaps you have seen their television commercials. The active ingredient is arginine, an amino acid which is found in saliva. It binds to the dentin surface which, in turn, attracts a calcium-rich layer from the saliva. This layer effectively clogs up the dentin tubules to prevent the movement of the fluid, thus causing a decrease in sensitivity.
It is administered as a paste in the dental office which is polished onto the sensitive teeth and then followed with the corresponding toothpaste to use at home. The office paste does indeed work very well. It provides immediate relief and, when followed with the toothpaste, will have a lasting effect.
So if you are tired of trying to cope with sensitive teeth associated with receeding gums, give us a call. We may be able to help make life a lot more enjoyable.
