You’ve been waiting all day to have some ice cream. You scoop out the right amount, settle down to eat it and when you do you see stars. Yow! That hurts. What was that and why did it happen?
The treatment of tooth sensitivity is a multibillion dollar industry only because so many people have it and want to get rid of it. Before you can get rid of it you need to know why your teeth are sensitive. Tooth sensitivity has a variety of causes. It can be caused by tooth decay, acidic foods, tooth whitening or bleaching, aggressive brushing and gum recession.
When someone has tooth decay you relieve the sensitivity by placing a filling in the tooth. Most of the time the sensitivity will go away right away and at most it may take a few days. As long as the cavity is not too deep, after the tooth is filled the problem is solved.
Acidic foods can lead to sensitivity because the acid starts a process called decalcification that dissolves the outside of the tooth enamel. It is similar to what happens when you have a cavity but in this case, the enamel has not completely broken down. If you use a toothpaste that can remineralize the tooth and there are many brands on the market, then the sensitivity can be reversed.
Some gum recession is normal as we age due to the normal chewing process where the muscles of the cheeks and gums pull the gums lower on the tooth. Overly aggressive toothbrushing can also lead to gum recession. Whatever the cause, gum recession can lead to a situation where the root of the tooth which is normally below the gumline is now above the gumline and exposed in our mouth. The root of the tooth is composed of cementum which is very porous. Everything goes right through cementum and it is why when there is recession the tooth gets very sensitive. In this case a toothpaste like Sensodyne or Colgate Pro Relief when used daily for a few weeks will help. These toothpastes contain minerals that plug the pores in the cementum and help to seal the tooth.
Finally, occasionally when people try to whiten their teeth with either home bleaching products or in the dental office, their teeth can get sensitive because of the chemicals in the whitening product. Usually the sensitivity will go away when you stop the whitening process. If you have sensitive teeth and are considering doing some whitening, you should use Sensodyne toothpaste for 2 weeks before you start and it may lessen the sensitivity.
As you can see there are many causes of sensitivity. It always helps to see your dentist who can diagnose the problem and get you on the way to enjoying that ice cream.
