Pain or Sensitivity
As the decay spreads, it can cause painful symptoms. With a cavity, you may experience pain when biting or chewing. You may notice that your teeth are more sensitive to warm or cold foods or beverages. This is because the hole in your tooth is exposed and the nerves are more susceptible to irritation. You will likely have a toothache around the area of the affected tooth. If the decay spreads to the pulp of the tooth, your dentist may need to perform a root canal.
Stains or Discoloration
As a cavity in your tooth progresses, you will be able to see signs of the damage. If you have a cavity, you can see and feel a hole or opening in your tooth. It is also common for the tooth to show signs of discoloration. A decayed tooth may have brown, black, or white stains.
In many cases, there are no early signs of cavities. If you experience symptoms, the decay has already progressed. Since cavities can go unnoticed for some time, it is important to see a dentist every six months for regular check-ups. At a check-up, your dentist will be able to provide a cleaning which can remove plaque build up that causes decay. During the check-up exam, a dentist will check all teeth for any signs of cavities and the need for more serious treatments such as a root canal.
