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.

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.

Because it requires jaw movement, eating can be difficult and painful if you have a temporomandibular joint disorder (TMD). During flareups you may switch to foods that are easier to eat but may be less nutritious than those you're giving up.
But there are ways to keep healthier foods in your diet while minimizing TMD discomfort. In many cases, it's a matter of preparing your food differently. Here are a variety of food groups known for their nutritional value and what you can do to prepare them for easier eating with TMD.
Fruits and Vegetables. You should peel any fruits or vegetables with hard or chewy skin like apples, peaches or cucumbers. Try chopping or pureeing fruits and vegetables you can eat raw to reduce their size and make them easier to chew. Vegetables like carrots, potatoes, broccoli or cauliflower can be cooked, then chopped or mashed.
Legumes and nuts. Pod-based vegetables like beans or peas provide a number of nutritional elements, as do nuts with their healthy fats. Your motto with these foods should be "Not too large and not too hard." Be sure then to cook, mash or puree legumes that are larger than a pea. With nuts, try nut butters for a softer serving than eating them out of the shell.
Protein and Dairy. Any meats like poultry or beef should be cut into bite-sized pieces; you can also moisten them with broths, gravies or sauces for easier chewing, or braise or stew them in liquid to tenderize them. You can also consume most milk, yogurt or cheese products you can tolerate. If you can't, try alternatives like meal replacement or whey protein beverages.
Grains. Prepare grains by cooking them until they're softened. Hot cereals like oatmeal offer a lot of nutrition and they're relatively easy to eat. Toast your bread and cut the slice into smaller pieces to minimize jaw movement.
One last tip: take your time while eating. A slower rate not only helps you enjoy your food more, it reduces the amount of work your jaws perform while eating. Less jaw work can help further ease the discomfort of TMD.
