If you're one of over 30% of Americans who wince in pain when eating and drinking certain foods and beverages, you may have tooth sensitivity. Although there are a number of possible causes, the most common place to look first is tooth dentin.
Lying just under the enamel, dentin consists of tiny tubules that transmit sensations like pressure or temperature variation to the nerves of the inner pulp. The enamel, the gums and a covering on the roots called cementum help dampen these sensations.
But over-aggressive brushing or periodontal (gum) disease can cause the gums to shrink back (recede) and expose the dentin below the gum line; it can also cause cementum to erode from the roots. This exposure amplifies sensations to the nerves. Now when you eat or drink something hot or cold or simply bite down, the nerves inside the dentin receive the full brunt of the sensation and signal pain.
Enamel erosion can also expose dentin, caused by mouth acid in contact with the enamel for prolonged periods. Acid softens the minerals in enamel, which then dissolve (resorb) into the body. Acid is a byproduct of bacteria which live in dental plaque, a thin film of food particles that builds up on teeth due to poor oral hygiene. Mouth acid may also increase from gastric reflux or consuming acidic foods or beverages.
Once we pinpoint the cause of your tooth sensitivity we can begin proper treatment, first and foremost for any disease that's a factor. If you have gum disease, we focus on removing bacterial plaque (the cause for the infection) from all tooth and gum surfaces. This helps stop gum recession, but advanced cases may require grafting surgery to cover the root surfaces.
You may also benefit from other measures to reduce sensitivity:Â applying less pressure when you brush; using hygiene products like toothpastes that block sensations to the dentin tubules or slow nerve action; and receiving additional fluoride to strengthen enamel.
There are effective ways to reduce your tooth sensitivity. Determining which to use in your case will depend on the cause.

Are you considering getting dentures but have a few questions about the process? Dr. Andrew Yoon, your Orange City, FL dentist at ABF Dental, shares some information about the denture process.
What are types of dentures are available?
Several types of dentures are available, including:
- Full Dentures: These dentures replace both your top and bottom teeth. They consist of a row of artificial teeth set in a pink base to match your gums. You will begin wearing these teeth when your mouth has healed fully.
- Immediate Dentures: Immediate dentures are placed in your mouth immediately after your teeth are pulled. In some cases, they may be used as temporary dentures until your mouth heals completely and you can begin wearing full dentures.
- Overdentures: Overdentures fit over tooth remnants. Although you may only have a few teeth fragments of remaining, these remnants often have strong roots that can provide stability for your new dentures.
- Implant-Supported Dentures: Implant-supported dentures are attached to dental implants that are placed in your jaw. Implants replace the roots of your teeth and bond to your jawbone. Luckily, you don't need an implant for every one of your missing teeth. Just two to four implants can support an upper or lower denture.
- Partial Dentures: Partial dentures are used if you have multiple missing teeth but don't need full dentures. These removable dentures feature tiny hooks that attach to the teeth on either side of the gap in your mouth.
How do I receive dentures?
Your Orange City dentist makes a mold of your mouth during the first step of the denture process. The mold is used to create dentures that fit your mouth exactly. If you will receive immediate dentures, your dentist places them in your mouth just after extracting your teeth. During the next few months, the fit of your dentures will need to be adjusted periodically to reflect the changes in your mouth as it heals.
When you're ready to receive permanent dentures, wax rims will be placed in your mouth first. Your dentist uses the rims to determine the correct bite and position of your artificial teeth. In a few days, you'll return to the office to test the fit of the dentures. Your new teeth will be temporarily attached to a wax base at this point. After your dentist makes any necessary adjustments, he'll send the base to your lab, and you'll receive your brand new permanent dentures two or three days later.
Are you ready to begin the denture process? Call Dr. Yoon, your Orange City, FL dentist at ABF Dental, at (386) 774-0125 to schedule an appointment.
Did you see the move Cast Away starring Tom Hanks? If so, you probably remember the scene where Hanks, stranded on a remote island, knocks out his own abscessed tooth — with an ice skate, no less — to stop the pain. Recently, Dear Doctor TV interviewed Gary Archer, the dental technician who created that special effect and many others.
“They wanted to have an abscess above the tooth with all sorts of gunk and pus and stuff coming out of it,” Archer explained. “I met with Tom and I took impressions [of his mouth] and we came up with this wonderful little piece. It just slipped over his own natural teeth.” The actor could flick it out with his lower tooth when the time was right during the scene. It ended up looking so real that, as Archer said, “it was not for the easily squeamish!”
That’s for sure. But neither is a real abscess, which is an infection that becomes sealed off beneath the gum line. An abscess may result from a trapped piece of food, uncontrolled periodontal (gum) disease, or even an infection deep inside a tooth that has spread to adjacent periodontal tissues. In any case, the condition can cause intense pain due to the pressure that builds up in the pus-filled sac. Prompt treatment is required to relieve the pain, keep the infection from spreading to other areas of the face (or even elsewhere in the body), and prevent tooth loss.
Treatment involves draining the abscess, which usually stops the pain immediately, and then controlling the infection and removing its cause. This may require antibiotics and any of several in-office dental procedures, including gum surgery, a root canal, or a tooth extraction. But if you do have a tooth that can’t be saved, we promise we won’t remove it with an ice skate!
The best way to prevent an abscess from forming in the first place is to practice conscientious oral hygiene. By brushing your teeth twice each day for two minutes, and flossing at least once a day, you will go a long way towards keeping harmful oral bacteria from thriving in your mouth.

You've been treating a persistent rash around your mouth with medicated ointments, but it's not going away. The problem may be the ointment — it could actually be sustaining the particular rash you have.
Peri-oral dermatitis is a scaly rash with small bumps (some filled with pus) around the mouth, eyes or nose. It's especially common among women ages 20-45, possibly due to hormonal factors or cosmetic use. Other than its unattractiveness you might not otherwise notice it, although it can cause stinging, itching or burning. There are ways to treat it effectively, though not necessarily the way you might think.
Many skin conditions respond well to topical steroids, like ointments or lotions containing hydrocortisone. But prolonged use of a steroid for skin irritations might actually increase risks for peri-oral dermatitis. Applying it to an existing rash may also deceive you — the steroid constricts some of the skin's tinier blood vessels, which will make the rash appear as if it's fading. The effect, though, usually doesn't last more than an hour. If you continue to use the steroid, the rash won't get better.
The key to alleviating peri-oral dermatitis requires treatment from a physician, dermatologist or dentist, who will also be able to accurately diagnose the specific skin condition you have. If it is peri-oral dermatitis, the first step is to stop using any topical steroids and only wash with mild soap or similar substitute. You'll have to be patient because the rash may at first appear to flare up and worsen before getting better.
Instead of steroids, we may prescribe antibiotics to help clear the rash, typically tetracycline. It may take several weeks of use before the rash begins to clear; as it does clear, you would either stop the antibiotic treatment or taper off over a four-to-five week period.
While some cases of peri-oral dermatitis will clear up and remain that way, some people may experience chronic reoccurrences. Even so, by using the same treatment approach we can still effectively manage the condition for the long-term.
