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.
Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment.

If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.
