Brushing and flossing daily, and dental visits at least twice a year: These are the essential things you should be doing to protect your teeth and gums against dental disease. But you're also getting an automatic assist from your body through saliva, that humble fluid swishing around in your mouth, to protect your oral health.
It's more than simply “mouth water”: Without saliva and its various components, your risk for tooth decay or periodontal (gum) disease would be much higher. Here are 4 ways saliva helps you keep your teeth and gums healthy.
Cleansing. Chewing prepares your food for digestion, but in the process produces tiny particles of food debris. Settling on tooth surfaces, these bits become part of the dental plaque that forms on your teeth and develops the ideal breeding ground for disease-causing bacteria. Saliva helps rinse away much of this debris—particularly sugar, the primary food source for bacteria.
Protection. Saliva is the first line defense against disease-causing microorganisms entering the mouth. The primary source of this protection is a protein-based antibody called Immunoglobulin A (IgA), which directly fights infection-causing organisms. Another protein in saliva, lactoferrin (also found in tears), interferes with bacterial growth.
Buffering. The main enemy of tooth enamel is mouth acid, produced by oral bacteria and the foods that we eat. Saliva neutralizes acid to help the mouth maintain its normally neutral pH range. And it works fast: Saliva can buffer acid and restore balance within thirty minutes to an hour after eating.
Re-mineralization. It's normal for acid to build up after eating, and for it to quickly remove minerals from surface enamel, a process called de-mineralization that can soften and weaken the enamel. But saliva helps restore some of these lost minerals as it's neutralizing acid. This re-mineralization re-strengthens enamel against tooth decay.
Saliva is so important for maintaining a healthy mouth, it's worth your efforts to protect it. Diminished saliva production not only produces an unpleasant dry mouth, it may increase your risk for disease. If this is a constant problem, speak to your dentist about causes and remedies. You'll be doing your teeth and gums a favor.

As far as your appearance goes, the most important teeth you have are those in the “smile zone.” These are the teeth most visible when you smile—and the ones that awkwardly stand out if they're chipped, worn or otherwise flawed. More than any other teeth, they determine how inviting your smile is to others.
You might think you'll need extensive cosmetic dental work to fix these kinds of dental defects. But that may not be necessary: We may be able to use a dental material known as composite resin to repair the defects in your “smile zone” teeth in one office visit.
Composite resins are a combination of ceramics and plastics that have been around for some time. They've only recently come into wide use, though, with the development of new techniques to bond them to tooth surfaces. They're ideal for chips, cracks, or decayed areas where front teeth make contact with one another. They may also be used occasionally to reshape irregular or misaligned teeth.
You'll first need a complete dental examination to determine if composite resin bonding is an appropriate approach for your situation. If so, we'll begin by preparing the tooth surface to better accept the resin material. We'll then apply the liquid form of the material in layers, along with other agents to increase the material's strength. Each layer is cured (hardened) before applying the next layer.
As the layers build up, we shape the material to achieve a normal tooth appearance. We'll also incorporate your individual color shadings, so that the prepared tooth blends well with surrounding natural teeth. In effect, the procedure requires as much artistry as technical skill to create a natural look.
Though not as strong as porcelain veneers or crowns, composite resins are durable if not subjected to heavy biting forces. And for a few hours in the dentist's chair with minimal tooth preparation, a composite resin treatment can create a dramatic and exciting change in your appearance.

Dentists and oral surgeons remove millions of teeth every year, most without any adverse aftereffects. But about 2% of patients experience a dry socket, a condition that, although not dangerous to health, can be quite painful.
Also known as alveolar osteitis, a dry socket occurs when the blood clot that normally forms right after extraction doesn't form or becomes lost later. The clot serves as a barrier for the underlying bone and nerves during the healing process; without it these tissues can become irritated from contact with air, food or fluids.
Dry sockets (which usually occur in the back, lower molars) are fortunately rare, mainly in patients over 25, smokers or women using oral contraceptives. Patients also have a higher risk of developing a dry socket if they attempt certain activities too soon after tooth extraction like vigorous chewing or brushing that may dislodge the protective clot.
You can reduce your chances of a dry socket after a tooth extraction with a few simple guidelines. Unless advised otherwise by your dentist, avoid brushing the day after extraction and gently rinse the mouth instead. It also helps to avoid hot liquids and eat softer foods for a few days. If you smoke, you should avoid smoking during this time and use a nicotine patch if necessary.
Over the next few days, you should remain alert for any signs of a dry socket, often a dull, throbbing pain that radiates outward toward the ears, and a bad taste or mouth odor. A prompt visit to the dentist will help alleviate these symptoms, often in just a few minutes.
To treat it, a dentist will typically irrigate the socket and apply a medicated dressing, which you would need to change every other day for up to a week. After that, you'll leave the dressing in place for a while as you heal.
A dry socket doesn't interfere with the healing process: Your extraction site will heal whether or not you have one. But prevention and treatment for a dry socket will help ensure your healing after an extracted tooth is much less uncomfortable.
