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.

A woman as gorgeous and funny as Sofia Vergara surely planned to be a model and actress from the get-go, right? Wrong! Sofia’s first career choice actually was to be… a dentist! That’s right, the sexy star of TV’s Modern Family actually was only two semesters shy of finishing a dental degree in her native Columbia when she traded dental school for the small screen. Still, dental health remains a top priority for the actress and her son, Manolo.
“I’m obsessed,” she recently told People magazine. “My son thinks I’m crazy because I make him do a cleaning every three months. I try to bribe the dentist to make him to do it sooner!”
That’s what we call a healthy obsession (teeth-cleaning, not bribery). And while coming in for a professional cleaning every three months may not be necessary for everyone, some people — especially those who are particularly susceptible to gum disease — may benefit from professional cleanings on a three-month schedule. In fact, there is no one-size-fits-all approach to having professional teeth cleanings — but everyone needs this beneficial procedure on a regular basis.
Even if you are meticulous about your daily oral hygiene routine at home, there are plenty of reasons for regular checkups. They include:
- Dental exam. Oral health problems such as tooth decay and gum disease are much easier — and less expensive — to treat in the earliest stages. You may not have symptoms of either disease early on, but we can spot the warning signs and take appropriate preventive or restorative measures.
- Oral cancer screening. Oral cancer is not just a concern of the middle aged and elderly — young adults can be affected as well (even those who do not smoke). The survival rate for this deadly disease goes up tremendously if it is detected quickly, and an oral cancer screening is part of every routine dental visit.
- Professional teeth cleaning. Calcified (hardened) dental plaque (tartar or calculus) can build up near the gum line over time — even if you brush and floss every day. These deposits can irritate your gums and create favorable conditions for tooth decay. You can’t remove tartar by flossing or brushing, but we can clear it away — and leave you with a bright, fresh-feeling smile!
So take a tip from Sofia Vergara, and don’t skimp on professional cleanings and checkups. If you want to know how often you should come in for routine dental checkups, please contact us or schedule an appointment for a consultation.
