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.

Parents have been dealing with their children's teething pain for as long as parents and children have been around. Along the way, the human race has developed different ways to ease the discomfort of this natural process of dental development. While most are good, common-sense measures, one in particular needs to be avoided at all costs—applying topical oral products to the gums containing Benzocaine.
Benzocaine is a topical anesthetic often found in oral products like Anbesol, Orajel or Topex to help ease tooth pain or sensitivity. The agent can be found in gel, spray, ointment or lozenge products sold over-the-counter. As an analgesic, it's considered relatively safe for adults to use.
But that's not the case with infants or younger children. Researchers have found a link between Benzocaine and methemoglobinemia, a potentially fatal blood condition. Methemoglobinemia elevates the amount of a hemoglobin-like protein called methemoglobin, which in high concentrations can lower oxygen levels being transported to the body's cells through the bloodstream.
Because of their smaller anatomy and organ systems, younger children can have severe reactions to increases in methemoglobin, which can range from shortness of breath or fatigue to seizures, coma or even death. That's why you should never use products with Benzocaine or similar numbing agents to ease teething pain. Instead, follow these common sense practices:
- Give your child chilled rubber teething rings, wet washcloths or pacifiers to chew or gnaw on. The combination of cold temperatures and pressure from biting on them will help ease the pain. Just be sure the item isn't frozen, which could cause frost burns to soft tissues.
- For temporary relief from soreness, gently massage your baby's gums with a clean, bare finger or with it wrapped in a clean, wet cloth. The massaging action helps counteract the pressure of the incoming tooth.
- For intense episodes of teething discomfort, ask your healthcare provider about using an over-the-counter pain reliever like acetaminophen or ibuprofen. Be sure you use only the recommended dose size for your child's age.
Teething is in many ways like a storm—it too shall pass. Be sure you're helping your baby weather it safely.
The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.
