One or more of the foods you eat could also be the cause of your halitosis. Spices such as garlic and onion are common culprits.

You could also have sensitive teeth because the enamel layer of your teeth is naturally thin. There are kinds of toothpaste and mouthwashes meant specifically for use with sensitive teeth. Your dentist might also recommend a fluoride treatment, crown, gum graft, or a root canal. The chosen treatment depends on the severity of your case.

A root infection is treated by a root canal. And, although many of us cringe in fear at the thought of having a root canal performed, the procedure is actually very safe with minimal pain since dentists use anesthetic while performing root canals.

Bruxism is the dental term for when you grind your teeth. Grinding most often occurs while you sleep but can also happen while you are awake. It can damage your teeth, cause you to develop jaw pain, and might even lead to headaches and earaches. What your dentist can do is give you a custom-made mouthguard to use at night.
