This is a question dentists hear frequently. The answer is that by visiting a dentist periodically, you'll keep visits short and you'll drastically reduce the likelihood of developing a problem.
Gum disease, for instance, is responsible for 60 percent of tooth loss in the country. And gum disease can get underway long before you would be aware of it. The same is true for decay. Only your dentist will be able to see the beginning of a cavity. Having a small decayed area repaired is much easier – and cheaper – to accomplish than is the repair of a large cavity, which may require some elaborate steps like root canal and a crown.
The general recommendation is that you visit your dentist twice a year. Even if there's no dental problem, it's good to at least have your teeth cleaned. That is simply the removal of any plaque that may be collecting on your teeth. Cleanings are important for the prevention both of decay and gum disease. The process will also leave your mouth feeling fresh and clean. Talk to your dentist about a checkup schedule that's right for you.
