Whether performed in a dental office or using a home kit, teeth whitening applications are quite effective for bleaching exterior (extrinsic) stains on enamel surfaces. But what if your discoloration comes from inside the tooth? In this case, extrinsic teeth whitening won’t work — you’ll need to undergo an “internal bleaching” method, which can only be performed in a dentist's office.
There are a number of causes for “intrinsic” staining, including too much fluoride exposure or tetracycline use during childhood. One of the more common causes, though, occurs from root canal treatments used to remove the remnants of the pulp tissue inside a tooth’s pulp chamber and root canals. Certain cements used during the procedure to help seal in the filling material and leftover blood pigments can cause the tooth to darken over time.
To alleviate this discoloration, we use a bleaching agent, usually sodium perborate mixed with a diluted solution of hydrogen peroxide to achieve a safe, accelerated color change. After determining that the root canal filling is still intact and the bone is healthy, we create a small cavity in the back of the tooth to access the pulp chamber. The chamber is cleaned of any debris or stained material and then thoroughly irrigated. The original root canal filling is then sealed off to prevent leakage from the bleaching agent.
We then place the bleaching agent in the cleaned-out space with a cotton pellet and seal it in with a temporary adhesive. This step is repeated for several days until we achieve the desired shade of white. Once that occurs we then seal the dentin with a more permanent filling and then restore the cavity we created with a composite resin bonded to the enamel and dentin.
If we’re successful in achieving the desired color, intrinsic whitening could help you avoid more costly options like veneers or crowns for an otherwise healthy and attractive tooth. The end result would be the same — a beautiful smile without those unsightly stains.

Sure, it’s big news when celebs tweet selfies from the dental office… if you’re still living in the 20th century. But in Hollywood today, it’s harder to say who hasn’t posted snaps of themselves in the dentist’s chair than who has. Yet the pictures recently uploaded to Twitter by Mark Salling, the actor and singer who regularly appears as Noah “Puck” Puckerman on the popular TV series Glee, made us sit up and take notice.
“Getting my chipped tooth fixed. Also, apparently, I’m a big grinder,” read the caption. The photo showed a set of upper front teeth with visible chips on the biting surface. What’s so special about this seemingly mundane tweet? It’s a great way of bringing attention to a relatively common, but often overlooked problem: teeth clenching and grinding, also called bruxism.
Although bruxism is a habit that affects scores of people, many don’t even realize they have it. That’s because the condition may only become active at night. When the teeth are unconsciously ground together, the forces they produce can wear down the enamel, cause chipping or damage to teeth or dental work (such as veneers or fillings), or even loosen a tooth! While it’s common in children under 11 years old, in adults it can be a cause for concern.
Sometimes, mouth pain, soreness and visible damage alert individuals to their grinding habits; other times, a dental professional will notice the evidence of bruxism during an exam or cleaning: tooth sensitivity and telltale wear and tear on the chewing surfaces. Either way, it’s time to act.
Bruxism is most often caused by stress, which can negatively impact the body in many ways. It may also result from bite problems, the overuse of stimulating substances (caffeine, alcohol, tobacco, and illegal drugs), and as a side effect of certain medications. Sometimes, simply becoming aware of the habit can help a person get it under control. Common methods of stress reduction include exercise, meditation, a warm bath or a quiet period before bedtime; these can be tried while we monitor the situation to see if the problem is going away.
If stress reduction alone doesn’t do the trick, several other methods can be effective. When bruxism is caused by a minor bite problem, we can sometimes do a minor “bite adjustment” in the office. This involves removing a tiny bit of enamel from an individual tooth that is out of position, bringing it in line with the others. If it’s a more serious malocclusion, orthodontic appliances or other procedures may be recommended.
When grinding is severe enough to damage teeth or dental work, we may also recommend a custom-made night guard (occlusal guard), which you put in your mouth at bedtime. Comfortable and secure, this appliance prevents your teeth from being damaged by contacting each other, and protects your jaw joints from stresses due to excessive grinding forces.
Whether or not you have to smile for a living, teeth grinding can be a big problem. If you would like more information about this condition, call our office to schedule a consultation for a consultation.
The National Safety Council has designated June as National Safety Month. A key component of staying safe is being prepared for emergencies, and this includes dental emergencies. Would you know what to do if you suffered any of the following dental mishaps?
Chipped tooth: One common dental injury is a chipped tooth. If this happens to you, save the missing chip if possible because we may be able to bond it back onto the tooth—but don’t be tempted to glue the chip back on by yourself! However, even without the missing chip, the tooth can most often be repaired with bonding material.
Cracked tooth: If you crack a tooth, rinse your mouth with warm water. If it is bleeding, hold a clean washcloth or gauze to the area until the bleeding stops, but don’t wiggle the tooth around or bite down hard. Keep in mind that the sooner your tooth is repaired, the better. Depending on how bad the crack is, if the tooth can be treated, it will most likely continue to function pain-free for years to come.
Displaced (“luxated”) tooth: If an injury causes your tooth to become loose, shoves it sideways or pushes it into or out of its socket, don’t try to force the tooth back into position on your own. Instead, call the dental office right away and leave it to us to bring the tooth back into its proper place and determine the extent of the injury.
Knocked out tooth: If a permanent tooth is knocked out of your mouth, pick it up without touching the root and rinse it off with cold water, but do not scrub. For the best chance of saving the tooth, place it firmly back in its socket within five minutes and hold it in position for a few minutes. If this is not possible, keep the tooth between your cheek and gum or in a glass of cold milk so that it doesn’t dry out. Call the dental office immediately.
If a baby tooth is knocked out, there is no need to place it back in the socket since baby teeth are not reattached. However, it is still important to have us examine the injury.
Being prepared for dental emergencies can help save a tooth as well as avoid more costly dental treatment down the road. But no matter what type of dental injury you have, it is important to come in for a consultation as the injury may extend beyond the part of the tooth that is visible. With today’s materials and technology, there’s a very good chance your smile can look as good as before—and often even better!
