Dental visit anxiety is a serious problem: Half of all Americans admit to some level of dental fear, while 15% avoid dental care altogether due to acute anxiety. The harm this can cause to dental health is incalculable.
But dentists have a number of sedation techniques that can relax anxious patients and allow them to receive the care they need. Although often used together, sedation is slightly different from anesthesia, which aims to deaden pain sensation. The aim of sedation is to calm the emotions and state of mind.
Sedation isn't a new approach: Physicians have used substances like root herbs or alcohol to relieve anxiety since ancient times. Modern dentistry also has a long history with sedation, dating from the early 1800s with the first use of nitrous oxide gas.
Modern dental sedation has expanded into an array of drugs and techniques to match varying levels of anxiety intensity. At the milder end of the scale are oral sedatives, taken an hour or so before a dental appointment to produce a calmer state. This may be enough for some patients, or it can be used in conjunction with nitrous oxide.
For those with more intense anxiety, dentists can turn to intravenous (IV) sedation. In this case, the sedative is delivered directly into the bloodstream through a small needle or catheter inserted in a vein. This causes a quicker and deeper reaction than oral sedatives.
Although similar to general anesthesia, IV sedation does differ in significant ways. Rather than unconsciousness, IV sedation places a patient in a “semi-awake” state that may still allow them respond to verbal commands. And although the patient's vital signs (heart rate, breathing, blood pressure, etc.) must be monitored, the patient doesn't need breathing assistance as with anesthesia.
There's one other benefit: The drugs used often have an amnesic effect, meaning the patient won't remember the treatment experience after recovery. This can be helpful in creating more pleasant memories of their dental experience, which could have its own sedative effect in the future.
Whether oral, gas or IV, sedatives are a safe and effective way to calm dental fears during treatment. That could help someone with anxiety maintain their oral health.

Professional Hockey player Keith Yandle is the current NHL “iron man”—that is, he has earned the distinction of playing in the most consecutive games. On November 23, Yandle was in the first period of his 820th consecutive game when a flying puck knocked out or broke nine of his front teeth. He returned third period to play the rest of the game, reinforcing hockey players’ reputation for toughness. Since talking was uncomfortable, he texted sportswriter George Richards the following day: “Skating around with exposed roots in your mouth is not the best.”
We agree with Yandle wholeheartedly. What we don’t agree with is waiting even one day to seek treatment after serious dental trauma. It was only on the following day that Yandle went to the dentist. And after not missing a game in over 10 years, Yandle wasn’t going to let a hiccup like losing, breaking or cracking nearly a third of his teeth interfere with his iron man streak. He was back on the ice later that day to play his 821st game.
As dentists, we don’t award points for toughing it out. If anything, we give points for saving teeth—and that means getting to the dentist as soon as possible after suffering dental trauma and following these tips:
- If a tooth is knocked loose or pushed deeper into the socket, don’t force the tooth back into position.
- If you crack a tooth, rinse your mouth but don’t wiggle the tooth or bite down on it.
- If you chip or break a tooth, save the tooth fragment and store it in milk or saliva. You can keep it against the inside of your cheek (not recommend for small children who are at greater risk of swallowing the tooth).
- If the entire tooth comes out, pick up the tooth without touching the root end. Gently rinse it off and store it in milk or saliva. You can try to push the tooth back into the socket yourself, but many people feel uneasy about doing this. The important thing is to not let the tooth dry out and to contact us immediately. Go to the hospital if you cannot get to the dental office.
Although keeping natural teeth for life is our goal, sometimes the unexpected happens. If a tooth cannot be saved after injury or if a damaged tooth must be extracted, there are excellent tooth replacement options available. With today’s advanced dental implant technology, it is possible to have replacement teeth that are indistinguishable from your natural teeth—in terms of both look and function.
And always wear a mouthguard when playing contact sports! A custom mouthguard absorbs some of the forces of impact to help protect you against severe dental injury.

Straightening your teeth with braces or other orthodontic gear is a positive step toward a healthier and more attractive smile. You'll likely be pleased with your smile when they're removed.
But you may also notice something peculiar once the braces are off—dull, white spots on your teeth. These spots, usually located under or around braces hardware, are where mouth acid has “demineralized” calcium and other minerals in the enamel. As beginning tooth decay, these spots are a sign your hygiene efforts weren't sufficient in cleaning your teeth of plaque.
In many cases, the spots will improve on their own after the braces are removed. We can also strengthen the enamel with fluoride pastes or gels, or inject tooth-colored resin within the spot to restore the enamel's translucence and improve appearance.
But the best approach is to try to prevent white spots from occurring at all. Here's what you need to do.
Keep up your oral hygiene. Even though more difficult with braces, you still need to brush and floss to protect your teeth from tooth decay. To make it easier, take advantage of special brushes designed to clean around orthodontic brackets and wires. A floss threader can also help you better access between teeth—or switch to a water flosser instead of floss thread.
Practice a “tooth-friendly” diet. A diet high in sugar and acid could short-circuit your best hygiene efforts. Certain beverages are big offenders: sodas, energy and sports drinks, and even “natural” juices. Instead, eat foods high in vitamins and minerals like fresh fruits and vegetables, lean proteins and low-fat dairy.
Get your teeth cleaned regularly. While you're seeing your orthodontist for scheduled adjustments, don't neglect regular cleanings with your family dentist. Professional cleanings at least every six months reduce the risk of dental disease. These regular visits are also a good time for your dentist to check your teeth for any signs of dental problems associated with your braces.
It's not easy to keep your teeth clean while wearing braces, but it can be done. With help from a few handy tools and continuing care from your dental professionals, you can avoid unsightly white spots.

A loose baby tooth is normal and expected; a loose permanent tooth is quite another matter: it’s an advanced sign of disease that could lead to losing the tooth.
The reasons for its looseness may vary. You may have experienced “primary occlusal trauma,” in which the teeth have experienced a prolonged excessive biting force beyond their tolerance. This can be caused by habitual grinding or clenching the teeth.
You may have also experienced “secondary occlusal trauma”: although the biting forces are within normal ranges, the teeth still can’t handle the stress due to degraded bone support and gum tissue detachment. Clenching habits combined with weakened bone and gums will only accelerate and worsen the damage.
The most frequent cause in adults for loose teeth is secondary trauma from periodontal (gum) disease. Bacterial plaque built up on teeth from poor oral hygiene causes a chronic infection that eventually weakens gum attachment to the teeth. A loose tooth is a late sign of this damage.
Treatment for disease-based loose teeth has a twofold approach. First, we thoroughly clean the tooth, root and gum surfaces of all plaque and calculus (hardened plaque deposits) to reduce the infection and inflammation and restore tissue health. This is often accompanied by antibiotic treatments to reduce bacteria below the gum tissue.
For the loose teeth themselves, we may need to modify the forces against them while the gums and bone heal. One way to lessen the biting force on a tooth is to reshape its and the opposing tooth’s biting surfaces. For extensive looseness we can also splint the affected tooth or teeth with other teeth. Temporarily, we can apply splinting material to the outside of both the loose and stable teeth or cut a small channel into them and apply bonding material to join them. A permanent option is to crown both the affected teeth and nearby stable teeth and fuse the crowns together.
These and other stabilizing techniques, like occlusal night guards to reduce the effects of teeth grinding or orthodontic treatment, will help secure the teeth. Coupled with disease treatment and renewed dental care and hygiene practices, you may be able to keep that loose tooth from being lost.

It’s true — thumb sucking beyond age 4 can cause bite problems for permanent teeth. But prolonged thumb sucking is just one of a number of possible contributing factors for a bad bite (malocclusion). A dentist must identify all the factors involved when a bad bite is present — their involvement is essential for a successful treatment outcome.
A fairly benign habit for infants and toddlers, thumb sucking is related to an “infantile swallowing pattern” young children use by thrusting their tongues forward between the upper and lower teeth when they swallow. Around age 4, though, they usually transition to an adult swallowing pattern in which the tongue rests on the roof of the mouth just behind the front teeth. Thumb sucking stops for most children around the same time.
Thumb sucking beyond this age, though, can put increased pressure on incoming permanent teeth pushing them forward. This could lead to an “open bite” in which the upper and lower teeth don’t meet when the jaws are closed. The tongue may also continue to thrust forward when swallowing to seal the resulting gap, which further reinforces the open bite.
Before treating the bite with braces, we must first address the thumb sucking and improper tongue placement when swallowing — if either isn’t corrected the teeth could gradually revert to their previous positions after the braces come off. Besides behavioral incentives, we can also employ a thin metal appliance called a “tongue crib” placed behind the upper and lower incisors. A tongue crib discourages thumb sucking and makes it more difficult for the tongue to rest within the open bite gap when swallowing, which helps retrain it to a more normal position.
An open bite can also occur if the jaws develop with too much vertical growth. Like thumb sucking and improper tongue placement, abnormal jaw growth could ultimately cause orthodontic treatment to fail. In this case, though, surgery may be necessary to correct the jaw structure.
With all these possible variables, our first step needs to be a thorough orthodontic exam that identifies all the cause factors for your child’s specific malocclusion. Knowing if and how thumb sucking may have contributed to the poor bite will help us design a treatment strategy that’s successful.
