Do you have cavities?
Cavities is basically tooth decay which occurs when food gets trapped between your teeth and is not properly removed while brushing and flossing.
The mouth bacteria cling on them and release acids which dissolve protective covering of your tooth and create holes.
Lots of sugary & acidic food stuffs and beverages, poor oral hygiene routine, dry mouth, not enough fluoride intake, eating disorders such as anorexia and bulimia and acid reflux disease in which acids from stomach can wear down the teeth are some of common causes of decay.
Cavities commonly develop in back teeth as they are harder to reach while brushing and flossing.
The dentist can find cavities during your regular dental checkup by probing the teeth to look for soft spots & using x-rays to check in between teeth.
If the cavity was present for quite a while, you might have toothache especially after eating or drinking something cold, hot or sweet.
You can sometimes also see pits and holes in teeth.
Depending on severity your dentist might advise you to go for fluoride treatment or dental filling, crown & root canal therapy.
To prevent tooth decay and cavity eat healthy, fiber rich fruits and veggies, food stuffs high in calcium; limit snacking in between your meals, consider getting sealants on teeth, brush regularly with fluoride toothpaste, fluoride supplements can also help prevent decay and keep your mouth clean and healthy, remember to change tooth brush every three months or when it wears off and schedule for a regular checkup at your dental office twice a year.
