Can whiteners damage your teeth? From an ADA link : "Well" spokesperson Dr. Edmond Hewlett weighs in for The New York Times.
There is no indication that frequent, long-term use of teeth whitening strips cause damage, said Dr. Denis Kinane, dean of the University of Pennsylvania School of Dental Medicine.
He said he was initially worried that repeated usage might damage cells within the dentin, the layer just beneath the enamel. But “there’s no evidence that there’s any detrimental effect,” he said.
Whitening strips bleach the part of the tooth just beneath the enamel, changing its color, though the effects are temporary. Coffee, wine and – especially smoking – can re-stain the teeth.
Whiteners may cause pain in sensitive teeth in the short term, especially for younger people. But any sensitivity is likely to go away once the whitening is stopped, said Dr. Edmond Hewlett, a spokesman for the American Dental Association and professor at the University of California, Los Angeles, School of Dentistry.
There would also be no biological reason for whitening strips or the tooth-whitening trays used by dentists to cause any harm in the long-term when used properly, he said. Their active ingredient is generally hydrogen peroxide, which breaks down in the body into water and a harmless compound called urea, he said.
Dr. Hewlett said he is more concerned about people trying to remove stains by overly aggressive brushing, which can damage the tooth structure and leave ruts that may lead to cavities.
People who are concerned about the color of their teeth should talk to their dentist about which product is right for them, and to ensure that the cause of discoloration isn’t tooth decay, he said.
Dr. Kinane said his only concern with whiteners is that many people – including his daughter – seem to get “addicted” to super-white teeth.
“Pure white is not what natural teeth look like,” he said.
Did you know 50% of people admit to some form of anxiety visiting the dentist, with roughly 1 in 6 avoiding dental care altogether because of it? To ease anxiety dentistry has developed sedation methods that help patients relax during dental treatment.
Many can achieve relaxation with an oral sedative taken about an hour before a visit. Some with acute anxiety, though, may need deeper sedation through an intravenous (IV) injection of medication. Unlike general anesthesia which achieves complete unconsciousness to block pain, IV sedation reduces consciousness to a controllable level. Patients aren’t so much “asleep” as in a “semi-awake” state that’s safe and effective for reducing anxiety.
While there are a variety of IV medications, the most popular for dental offices are the benzodiazepines, most often Midazolam (Versed). Benzodiazepines act quickly and wear off faster than similar drugs, and have a good amnesic effect (you won’t recall details while under its influence). While relatively safe, they shouldn’t be used with individuals with poor liver function because of their adverse interaction with liver enzymes.
Other drugs or substances are often used in conjunction with IV sedation. Nitrous oxide (“laughing gas”) may be introduced initially to help with anxiety over the IV needle stick. Sometimes pain-reducing drugs like Fentanyl may be added to the IV solution to boost the sedative effect and to reduce the amount of the main drug.
If we recommend IV sedation for your dental treatment, there are some things you should do to help the procedure go smoothly and safely. Because the after effects of sedation may impair your driving ability, be sure you have someone with you to take you home. Don’t eat or drink anything after midnight the day before your appointment, and consult with both your physician and dentist about taking any prescription medication beforehand. Wear loose, comfortable clothing and don’t wear contact lenses, oral appliances like dentures or retainers, watches or other jewelry.
Our top priority is safety — we follow strict standards and protocols regarding IV sedation and you’ll be carefully monitored before, during and after your procedure. Performed with the utmost care, IV sedation could make your next dental procedure pleasant and uneventful, and impact your oral health for the better.
So you’re tearing up the dance floor at a friend’s wedding, when all of a sudden one of your pals lands an accidental blow to your face — chipping out part of your front tooth, which lands right on the floorboards! Meanwhile, your wife (who is nine months pregnant) is expecting you home in one piece, and you may have to pose for a picture with the baby at any moment. What will you do now?
Take a tip from Prince William of England. According to the British tabloid The Daily Mail, the future king found himself in just this situation in 2013. His solution: Pay a late-night visit to a discreet dentist and get it fixed up — then stay calm and carry on!
Actually, dental emergencies of this type are fairly common. While nobody at the palace is saying exactly what was done for the damaged tooth, there are several ways to remedy this dental dilemma.
If the broken part is relatively small, chances are the tooth can be repaired by bonding with composite resin. In this process, tooth-colored material is used to replace the damaged, chipped or discolored region. Composite resin is a super-strong mixture of plastic and glass components that not only looks quite natural, but bonds tightly to the natural tooth structure. Best of all, the bonding procedure can usually be accomplished in just one visit to the dental office — there’s no lab work involved. And while it won’t last forever, a bonded tooth should hold up well for at least several years with only routine dental care.
If a larger piece of the tooth is broken off and recovered, it is sometimes possible to reattach it via bonding. However, for more serious damage — like a severely fractured or broken tooth — a crown (cap) may be required. In this restoration process, the entire visible portion of the tooth may be capped with a sturdy covering made of porcelain, gold, or porcelain fused to a gold metal alloy.
A crown restoration is more involved than bonding. It begins with making a 3-D model of the damaged tooth and its neighbors. From this model, a tooth replica will be fabricated by a skilled technician; it will match the existing teeth closely and fit into the bite perfectly. Next, the damaged tooth will be prepared, and the crown will be securely attached to it. Crown restorations are strong, lifelike and permanent.
Was the future king “crowned” — or was his tooth bonded? We may never know for sure. But it’s good to know that even if we’ll never be royals, we still have several options for fixing a damaged tooth.
