Is it possible to get a cavity beneath a crown?


I have a tooth that has been crowned for 4 years or so. It’s been hurting consistently, so I went to my dentist. She says there is a cavity beneath the crown. I thought crowns protected teeth, so how could there be a cavity in the tooth? – Shelli

Shelli – It is possible to get a cavity beneath crown, but it’s unusual to get the cavity beneath a crown that is only four year sold.

When a crown is placed, the margin—where the crown meets your tooth—should have no gaps. The smallest gap will leave room for plaque. Plaque will attract decay.

Insurance companies usually require that a crown be in place five years before it is replaced. Dentists expect crowns to last much longer than that.

We recommend that you have the crown examined by a skilled cosmetic dentist.

Bulimia and Your Teeth


More than 10 million Americans suffer from eating disorders, such as anorexia or bulimia.

Bulimia is characterized by excessive over-eating in a short amount of time. Excessive eating is often followed by self-induced vomiting.

In time, the vomiting—whether it’s caused by bulimia or another condition—will affect your teeth. The acid from vomiting will cause teeth to become discolored, thin and weak, and they may begin to crumble.

There are some things you can do to protect your teeth. Immediately after vomiting, your teeth are weak, so avoid brushing them at that time. Instead, thoroughly rinse your mouth with warm baking-soda water to neutralize the acid in your mouth. If baking soda is not available, rinsing your mouth with just water can help. Sip water throughout the day to keep your mouth moist. A dry mouth can’t fight bacteria and decay.

If you are struggling with, or recovering from, bulimia, tell your dentist. He or she will take steps to help you preserve your teeth. Fluoride treatments can help strengthen your teeth and protect them from decay.

If you’re recovering from bulimia and you want a smile makeover, the treatment varies depending on the extent of the damage to your teeth. Porcelain crowns can be made to completely cover and protect your teeth. They will have the translucency and color of your natural teeth. If you have lost teeth, dental implants are the most natural looking and natural feeling way to replace them. After examining your teeth, your dentist will discuss your options with you.

You will get the most natural-looking restoration from an experienced cosmetic dentist who is skilled in designed smile makeovers.
