If you wince in pain while eating or drinking something hot or cold, you’re not alone: tooth sensitivity afflicts one in three Americans. To understand what’s possibly going on, let’s look first at tooth anatomy.
Teeth are mainly composed of three layers: an outer protective enamel that covers the upper crown, a middle layer called dentin and an inner pulp. The dentin is composed of small tubules that transmit outer temperature and pressure sensations to nerves in the pulp.
The enamel serves as a “muffler,” damping sensations to protect the nerves from overload. In the root area, the gums and a thin material called cementum covering the roots also help muffle sensation.
But sometimes teeth can lose this muffling effect and the nerves encounter the full brunt of the sensations. The most common reason is gum recession, usually caused by periodontal (gum) disease. The gums have shrunk back or “receded,” and after a short while the cementum covering will also be lost, exposing the dentin in the root area.
Another problem is enamel erosion caused by mouth acid. Chronic high acidity, often caused by bacterial growth or acidic foods and beverages, can dissolve the enamel’s mineral content, causing decay and exposure as well of the underlying dentin.
To avoid future tooth sensitivity, it pays to prevent these two dental problems. The most important thing you can do is practice daily brushing and flossing to reduce bacterial plaque and see your dentist regularly for dental cleanings and checkups.
But if you’re already experiencing symptoms, you’ll first need an accurate diagnosis of the cause. If it’s related to gum disease, immediate treatment could help stop or even reverse any gum recession. To address enamel erosion, your dentist may be able to protect and strengthen your teeth with sealants and topical fluoride.
There are also things you and your dentist can do to reduce your symptoms. One is for you to use hygiene products with fluoride, which can take the edge off of sensitivity, or potassium, which helps reduce nerve activity. Your dentist can further reduce nerve sensitivity by blocking the tubules with sealants and bonding agents.
Tooth sensitivity is an irritating problem in itself; more importantly, though, it’s often a warning of something else seriously wrong that needs attention. If you’re feeling a little sensitive in the teeth, see your dentist as soon as possible.

After living with braces for a couple of years, the “big reveal” finally happens and you see your new smile for the first time. But then you’re told you have to wear another mouth appliance—around the clock to start and then just at night. After all the new smile excitement, wearing a retainer can be a little anticlimactic.
But this part of your orthodontic treatment is as important as the earlier tooth movement phase. That’s because your new “forever smile” doesn’t necessarily come with a “forever” guaranty. In fact, your teeth could quickly begin moving back to where they were before braces if you don’t wear a retainer.
The reason why is because of a tough but elastic gum tissue called the periodontal ligament. This ligament lies between the teeth and the jawbone, attaching to both through tiny extending fibers. The periodontal ligament actually does most of the anchoring work to hold your teeth in place.
The ligament is also why we’re able to move your teeth to different positions: As braces apply pressure to the teeth and jaw in the direction of desired movement, the ligament remodels itself to allow the teeth to take up these new positions.
The tissues involved, though, still retain a kind of “memory” of where the teeth used to be. This creates an immediate tendency for the teeth to revert to these old positions. To prevent this, we use a retainer that when worn keeps or “retains” the teeth in their new positions until they’ve stabilized and the old tissue “memory” fades.
There are different types of retainers, some removable and some fixed in place. Choosing the best one for a particular patient will depend on the complexity of the bite treatment, the patient’s age and level of self-responsibility and the preferences of the orthodontist. Whichever type of retainer you eventually use, it’s important you wear it to preserve all of the time and effort that went into transforming your smile.
Wearing a retainer might not be high on your “exciting things to do” list. But it’s the best way to guarantee you’ll enjoy your new smile for years to come.

The smiley face: It’s been around forever. Except it hasn’t—someone created it. No, not Forrest Gump (but good guess!), but graphic artist Harvey Ball in 1963 to help boost employee morale at an insurance company. Do you know what else Harvey Ball came up with? World Smile Day: Beginning in 1999, Ball began promoting the first Friday in October as a day to encourage smiles and acts of kindness. But there’s no need to limit smiles to one day. We hope you treat every day as World Smile Day—to make your corner of the world a little brighter.
What can you do to show your support? Well to begin with, smile—a lot. And also do things to make other people smile. We don’t want you to hold back because you’re not completely satisfied with your smile. If you’d like to get that wonderful smile of yours in better shape, here are some ideas:
Have your teeth professionally cleaned. Having your teeth cleaned at the dental office is one of the best things you can do to prevent dental disease. Dental plaque makes your teeth look dull and dingy and can lead to gum disease and cavities. A professional cleaning to rid your teeth of any built-up plaque and tartar (hardened plaque) with a follow-up polish can help your teeth look great!
Brighten up your smile. You can turn up the brightness volume on your teeth with a tooth whitening application. There are whitening products you can buy over the counter, but for best results see your dentist for a professional whitening. Dentists can better control the degree of brightness and their professional-grade solutions often last longer.
Upgrade your teeth’s appearance. You may have a great looking smile—except for that chip, discoloration or slight gap between a couple of teeth. There are a number of ways, many quite affordable, to improve your teeth’s appearance. Your dentist can bond color-matched composite resin to your teeth to “fill in” chips or other blemishes. And a veneer, a thin layer of porcelain bonded to the face of a tooth, can mask mild to moderate dental blemishes.
There are other “smile changers” like orthodontics, crowns or dental implants that are a bit more extensive. Depending on your needs and expectations, these can give you a “smile makeover” that will get you ready for future World Smile Days.
In the meantime, talk to us about how you can perk up your smile. An attractive smile is much easier to share with the world.
