Restoration Reality Check: Avoiding Replacement Could Cost You

One of the questions we get asked frequently is:

Why do I need to replace my filling (or crown)? I thought it would last forever?

As much as we would love to be able to promise that to you, we can’t. Even with the highest quality materials and techniques, which of course Dr. Kazerooni uses, fillings and/or crowns (also called restorations) aren’t permanent. Why? Well, for the same reason why your natural tooth structure doesn’t always last forever. Thousands, even millions of bacteria are introduced in your mouth daily. Yuck! Bacteria are present in a thin film called plaque, and when not cleaned off properly, plaque will cause decay in the tooth.

A few years after placing restorations, we start to see general wear and tear, causing the seal of the restoration to break down. There is no way to know exactly when this will happen since every mouth is different. Bacteria can then work their way between the worn filling and tooth and can’t be easily removed with a toothbrush and floss. Decay will start to develop along the edge of the filling and even underneath it. This is when your dentist in McLean VA will recommend you have the restoration replaced.

What can happen if I don’t get it treated?

• You can lose more tooth structure. When a tooth has decay left untreated, that area will get weak and then it will break.
• You may need an even larger restoration. For example, you may need to go from a filling to a crown. Usually when you lose more than 50% of tooth structure, a crown is recommended to help strengthen the tooth.
• The nerve of the tooth can get infected. If the decay reaches the nerve, or dental pulp, most likely the tooth will need a root canal treatment.
• Worst case scenario, which happens more often than you might think: You could lose the whole tooth. Depending on where it’s located and how large the decay gets, there’s a chance you will need to have the tooth extracted.

How do I ensure a longer life for my restorations?

• Brush twice daily and floss once a day.
• Drink water and/or chew sugarless or Xylitol gum after meals.
• Keep your teeth and gums in good health by visiting your hygienist regularly.
• Get your teeth checked 1‐2 times a year by your McLean dentist, Dr. Kazerooni. Some patients with higher decay rate may require more frequent visits to the dentist.
• Have X‐rays taken at least once a year.
• If recommended by Dr. Kazerooni, use fluoride toothpaste to help strengthen your tooth enamel.
• Ask us about a preventative treatment called sealants to help prevent getting cavities to begin with.
