Can an Electric Toothbrush Loosen a Crown?

After getting teeth whitening and new crowns, I invested $150 in an electric toothbrush in July, and I think it loosened my crown. I received two crowns in May, and one is loose. I intended to take good care of my teeth and minimize cavities because I want to stay out of the dental office unless it’s necessary. But within the past two weeks, I’ve felt my crown loosening. The loose one is a crown on a post. I stopped using the toothbrush already, but are the vibrations known to loosen crowns? I wish I had asked about this before spending money on the toothbrush. Thank you. Giada B. from NJ

Giada,

Sonic vibrations in electric toothbrushes help loosen plaque, but they are not strong enough to loosen the cement from your dental crown.

Dentists use high-powered ultrasonic scalers to remove a cemented dental post from a tooth. But the tip is rigid and transfers the full strength of the vibrations wherever a dentist applies it. Even with this instrument, a dentist must press firmly on the post for an extended period to loosen a post.

The vibrations of an ultrasonic or sonic toothbrush are gentle. If your post and crown are cemented properly, the toothbrush will not loosen them. But a loose dental crown is a problem. Schedule an appointment with your dentist right away. He or she will remove your new crown and determine why it is loose.

You received your crowns in May—so they are not old or worn and should not be loose. It seems that something went wrong in the cementing process, and your dentist must stabilize your crown to prevent damage to it, your bite, and other teeth.

If your dentist can’t resolve the issue, schedule a second opinion with an advanced cosmetic dentist with training in occlusion and bite. Hopefully, it will not be long before you can enjoy your brighter smile and new crowns.

Four Facts about Free Teeth Whitening and Dental Implants

Before and after photos for information on free teeth whitening, from Plano TX dentist Miranday Lacy DDS.
Only your natural teeth will respond to whitening

A whiter brighter smile is one of the top ways people want to improve their teeth. Many people look for do-it-yourself whitening kits or even free teeth whitening.

But there are questions about how the bleaching gel will affect existing dental work. What results can you expect with free teeth whitening if you have dental implants?

What Can You Expect?

  1. Dental implant crowns are usually made from porcelain or another material that is colorfast and doesn’t respond to attempts to whiten them. Crowns are stain resistant, but they can’t be penetrated by bleaching gel.
  2. Sometimes, a dental lab can change the color of crowns, but the original color is baked in, so even if it can be changed, it the color would be darker, not lighter.
  3. Depending on the position of your natural teeth in relation to the implant crowns, whitening your teeth may not be a problem. If your implants are toward the back of your mouth, people probably won’t notice that your natural teeth are much whiter.
  4. It is possible to get your teeth as white as you want them and later replace the implant crowns to match them. But if the crowns are being replaced for cosmetic reasons only, your insurance company probably won’t offer any benefits toward the replacement, unless your implant crowns are old.

Before You Start the Whitening Process

Bottom line: You can whiten your teeth if you have dental implants, but only your natural teeth will whiten. You should consider the position of your natural teeth in relation to the implant crowns. The dental implant crowns will not whiten, and replacing them for a color match can be costly.

If you have received a free teeth whitening kit, check the contents of the bleaching gel. The most common whitening agent is carbamide peroxide. If your bleaching gel contains a different whitening agent, research it for safety. Also check online to see what other users say about the gel in your bleaching kit.

Your dentist can provide safe, predictable results. Speak with him or her about how teeth whitening can be made affordable for you.
