What do i do to stop teeth decay ?
Your teeth will continue to decay if you don't take good care of them; cleaning thoroughly after meals and flossing. If there is decay, it needs to be repaired. After that, you need to change your eating habits; especially if you are drinking sugary drinks, eating sweets and hard candy and not brushing afterwards. Cut back on the sugar. Eat fruits and vegetables and anything that will help with your calcium intake. Take calcium tablets to strengthen your bones. If you are taking antibiotics (especially tetracycline, it can cause your teeth to change color and appear dark or yellow). It takes work to keep your teeth in good shape. You should have your gums checked, as well. You could have periodontal disease which causes your teeth to decay and become loose in your mouth. See your dentist and he can advise you about what is the best program for you and your dental situation. Changing your diet alone is not the answer; you have to change the way you have been treating your teeth (or not treating your teeth). There are solutions they can paint on your teeth after they have been repaired that will keep decay from forming on the tooth but only if you are doing all the right things to keep your mouth healthy. (Another issue which may not even be necessary to tell you is that any drug use (cocaine in particular) will rot your teeth at the gumline). It looks nasty and is a sign of drug use. Another reason to say, "If you use; you lose!". Hopefully, that isn't anything you even have to think about.
Reply:Try the sensitive tooth pastes - those with fluoride that helps seal the enamel. Milk, calcium products and cut down on the sweets. Brush often. Get the cavities filled - only the small start up ones have a chance to stop on their own, ones that have already made a hole need to be filled.
Reply:Brush teeth twice a day with fluoride toothpaste and don't eat sugary food. From http://aches.in/preventtoothache.html
Reply:Use ACT floride rinse. It will prevent your teeth from decaying any further.
Reply:brush your teeth after every meals. wait twenty minutes if you had something acidic. try chewing sugar free gums or xylitol sweetened gums if you can't brush. cheese are good for your teeth.
