Home whitening kits are a popular way to turn a dull smile into a dazzling one. But these self-applied products only work for teeth with outer enamel stains — if the discoloration originates inside a tooth, you’ll need professional treatment.
Known as “intrinsic staining,” this type of discoloration most often occurs within a tooth’s pulp or dentin layers. There are a number of causes like tooth trauma or tetracycline use at an early age. A root canal treatment used to remove infection from deep within a tooth can also cause discoloration: sometimes blood pigments left after tissue removal or the filling materials themselves can stain a tooth’s interior.
Intrinsic staining can often be treated by placing a bleaching agent, usually sodium perborate, into the tooth’s pulp chamber. But before undertaking this procedure on a tooth that’s undergone a root canal treatment,Â we want to first ensure the filling is intact and still adequately sealing the tooth from infection. We also want to make sure the supporting bone is also healthy.
If all’s well, we access the pulp in the same way as the root canal treatment, and preferably through the same access hole. We then clean out the pulp chamber of any stained matter and then ensure the root canals remain filled and sealed off from the pulp chamber.
We can then place the bleaching agent into the pulp, a process that will need to be repeated every three or four days to achieve the desired level of brightness. After each session we place a cotton pellet over the opening and held in place with a temporary adhesive; we can easily remove and re-apply this covering during subsequent sessions. Once we’ve achieved the desired color change, we seal the tooth with a permanent filling and restore the access cavity with a tooth-colored composite resin material bonded to the enamel and dentin.
There are other options for an intrinsically stained tooth like veneers or crowns that outwardly cover the discoloration. Internal bleaching, however, is a more conservative approach that causes less alteration of the tooth. If successful, it can restore a stained tooth to a brighter, more attractive shade.

Like other aspects of our lives, aging can take a toll on our smile. Over a lifetime the effects of disease, teeth wearing and the foods we eat can cause our teeth and gums to look unattractive.
Here are 3 of the most common age-related dental problems and how we can help you "turn back the clock" on each one.
Discoloration. Teeth can dull and grow darker over time. And not just from what we eat or drink—age-related structural changes in the tooth can also cause discoloration. We can often alleviate external staining temporarily with teeth whitening. If the staining is heavy or it originates inside the tooth, then we can install life-like porcelain veneers or crowns to cover the discoloration. We can also use composite dental materials to alter the color of one darkened tooth so that it doesn't stand out from the rest of your teeth.
Wearing. Our teeth naturally wear down over time. If the wearing is excessive, though, teeth can look shorter and less youthful. Again, we can use veneers or crowns to change a tooth's outward appearance and make them look longer. We can also employ enamel contouring and reshaping that smoothes out sharper edges caused by wearing to give your teeth a softer, more youthful look.
Receding gums. On the other end of the spectrum, gums that have shrunk back or receded from the teeth can make them look much larger and unattractive. Our first step is to treat any gum disease present—the most common cause of recession—which often helps the tissues to regenerate. If your case is more advanced, though, you may also need grafting surgery to restore lost gum tissue. Using in-depth microsurgical techniques, surgeons attach grafted gum tissue at the recession site. Over time new tissue will grow, restoring adequate gum coverage.
You can also improve your appearance at any age with orthodontics. Besides a more attractive smile, properly aligned teeth tend to wear more slowly and evenly. This and proper daily oral hygiene and regular dental care can keep your teeth looking younger even in your later years.
