How Can I Protect My Dental Crowns from Tooth Decay?

Posted on: 20 November 2017


When a dentist places a dental crown over a tooth, it is their job to ensure that the crown fits well so that it is sealed at the margins. This prevents bacteria from gaining entry to the area beneath the crown and protects the tooth from tooth decay. However, once you leave the dental office, it is then up to you to make sure that the tooth stays healthy.

If you want to make sure that your dental crowns last for many years to come, then make sure you keep the following factors in mind.

Brush and Floss the Margins Regularly

First of all, you should understand that without bacteria, there is no tooth decay. Unfortunately, it is presently impossible to remove all the bad bacteria from your mouth without harming the good bacteria. Therefore, it is up to you to make sure that bacterial organisms cannot build up in the area between the crown and the remaining natural tooth.

When you brush your teeth, brush the area where the crown meets the tooth. If this area is below the gum line, brush at a forty-five degree angle so that the bristles are able to reach the margin to remove any food debris or bacteria. Brush softly to avoid irritating the gum tissue. When you floss, gently floss along the margins to remove bacteria and food debris.

Cut down on Sugary Foods

Although you can't eradicate all the tooth decay-causing bacteria, you can reduce their food source. Basically, if bacteria cannot eat, they cannot produce the waste product (acid) that eats away at your tooth enamel. Try to cut down on sugary foods and drinks and if you cannot, make sure that you drink plenty of water after consuming sugar-rich foods.

The water will wash away some of the debris, depriving the bacteria of their food source.

Go for Dental Cleanings 2-4 Times Per Year

Sometimes, you need a professional set of eyes to ensure that the area is clean and free of bacteria. A dental hygienist is trained to spot tartar and areas that might be conducive to bacteria build-up. Visit a hygienist 2-4 times per year to have all your teeth cleaned. They will also be able to advise you if you think that an area of your crown is causing food to become lodged. They will then refer you to your dentist to have the area altered.

If you work with your dentist or hygienist while keeping your crowns clean, your dental crown can last you at least 10 years. Otherwise, you may find that the crown needs replacing much sooner than that.
