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.

Before we begin correcting a malocclusion (poor dental bite), we need to ask a few questions: How extensive is the malocclusion? How far must we move the teeth to correct it? How might the patient's jaw size impact treatment?
Answering these and other questions help us develop an effective treatment plan. And depending on the answers, we might need to look at other procedures before we install braces—like removing one or more of the teeth.
This isn't a subject to approach lightly: All teeth play an important role in dental function and smile appearance, and ordinarily we want to preserve teeth, not remove them. Sometimes, however, it may be a necessary action to achieve our goal of an improved dental bite.
For example, it might be necessary for correcting a malocclusion caused by severe teeth crowding. This occurs when one or both of the jaws hasn't grown to a sufficient size to accommodate all of the teeth erupting on it. As a result, some of the teeth could come in out of their proper alignment.
If caught early before puberty, we may be able to use other techniques to alleviate crowding, like a device called a palatal expander that influences an upper jaw to widen as it grows. If successful, it could provide later teeth more room to erupt in their proper positions.
But even if additional jaw growth occurs, it may not be enough to avoid a malocclusion or treatment with braces. Alleviating further crowding by removing teeth in little noticed areas could help with subsequent orthodontics.
Removing teeth may also be the answer for other problems like an impacted tooth, in which the tooth has not fully erupted and remains submerged in the gums. It's sometimes possible to use a technique to “pull” the tooth down where it should be; but again, that will still require jaw space that may not be available. The more effective course might be to remove the impacted tooth.
Whether or not tooth extraction will be needed can depend on a thorough orthodontic evaluation and full consideration of all the available options. Even though the ideal situation is to correct a bite with all teeth present and accounted for, it may be for the better good to sacrifice some.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.
