Advances in dentistry mean that we are able to detect a number of potential problems very early. If this is done, then the possibility of a successful cure becomes much higher than it would have otherwise been if the problem was detected late.
We screen for Oral Cancer using ultraviolet light or other advanced devices that allow us to see problems well before they would be visible to the naked eye under normal conditions.
The possibility of oral cancer and other disorders of mouth tissues are high in people who dring or smoke excessively. If you belong to that group, it wold be wise to get regular checkups when you visit your dentist.
