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.

On the way to adulthood, permanent teeth steadily erupt until, if all goes normally, you have a full set of teeth. Sometimes, though, one or more teeth may fail to form. This not only can affect your dental health, but it could also diminish your smile.
For example, if the lateral incisors on either side of the central incisors (the two teeth front and center) don't develop, it could create a smile that's “not quite right.” But we can vastly improve such a smile in one of three unique ways.
The first is to fill the resulting gap through canine substitution. This is an orthodontic method in which we use braces to move the pointed canine teeth, which normally position on the other side of the missing laterals, closer to the central incisors. This choice is determined by the size of the canine teeth. If they are slim in width, they can be re-shaped to make them appear more like a lateral incisor, and the gums possibly reshaped as well around them through cosmetic surgery.
We can also install a dental bridge, an appliance that fills the missing lateral space with prosthetic teeth. A traditional bridge requires the teeth on either side of the gap to be reduced in size, which becomes a permanent alteration to accommodate these crowns. This is a disadvantage in a young person. We can also use a “bonded bridge” which uses adhesives to attach extended pieces (or “wings”) of dental material from either side of the prosthetic tooth to one or more supporting teeth. These wings are behind the permanent teeth. Though not as durable as a traditional bridge, it does avoid altering the support teeth.
Finally, we can replace the missing teeth with dental implants. In this method, we install titanium metal posts into the jawbone at the missing tooth locations and then attach a life-like crown to each one. Implants may be more costly than other restorative methods and can take several months to complete. But they are life-like, highly durable, and don't require any alteration to other teeth. A disadvantage is that you should wait until at least 19 years of age to consider this option. What many people do is use a temporary solution until the proper age to do a dental implant.
Each of these methods have their advantages and disadvantages, which should be thoroughly reviewed in consultation with your dentist. And each may also require other dental work, such as initial orthodontics to open adequate space for a restoration. But any of these methods for correcting a missing lateral tooth can be effective and help restore both a healthier mouth and a more attractive smile.

Keeping your teeth and gums healthy doesn't require an elaborate plan. It's simple: Besides twice-a-year dental visits, the most important thing you can do is brush and floss every day to remove accumulated dental plaque.
The bacteria that live and breed in this thin biofilm is the main catalyst for both tooth decay and gum disease, the top two diseases that endanger teeth. Brushing and flossing removes this buildup and thus reduces the long-term risk for either disease.
Unfortunately, the message on these important hygiene tasks hasn't resonated with “Millennials,” the first generation to reach adulthood in the 21st Century and new millennium. One recent survey of 2,000 members of this age group found only about 30% brushed their teeth at least once a day, with many skipping the task for two days at a time.
If brushing has taken a beating among millennials, you can well imagine the state of flossing. Unfortunately, the news media has helped this along: Just a few years ago, the Associated Press reported a study that concluded flossing's role as a dental disease deterrent hadn't been proven. A follow-up study a year or two later by the University of North Carolina pushed back on the original AP story with findings of lower risk of tooth loss among flossers than non-flossers.
This decline in oral hygiene practices among millennials has had an unsurprisingly negative effect. Recent statistics indicate that one in three people between the ages of 18 and 34 have some form of untreated tooth decay. As this generation ages this may inevitably result in more extensive dental treatment and higher rates of tooth loss unless the trend toward hit and miss dental care makes a complete U-turn.
The good news is that it may not be too late for many of those slacking on daily care. All that's needed is to heed the same dental advice their grandparents and parents were given: Brush twice and floss once every day.
No matter what your age, consistent daily brushing and flossing still remains essential to keeping potential dental disease at bay. These twin hygiene tasks remain the solution to good dental health throughout your life.
