If your dentist found tooth decay on your last visit, you might have been surprised. But tooth decay doesn't occur suddenly—it's a process that takes time to unfold.
It begins with bacteria—too many, that is. Bacteria naturally live in the mouth, but when their populations grow (often because of an abundance of leftover sugar to feed on) they produce high amounts of acid, a byproduct of their digestion. Too much acid contact over time softens and eventually erodes tooth enamel, making decay easier to advance into the tooth.
So, one important strategy for preventing tooth decay is to keep your mouth's bacterial population under control. To do that, here are 4 common-sense tactics you should perform between dental visits.
Practice daily hygiene. Bacteria thrive in dental plaque, a thin film of food particles that builds up on teeth. By both brushing and flossing you can reduce plaque buildup and in turn reduce disease-causing bacteria. In addition, brushing with a fluoride toothpaste can also help strengthen tooth enamel against acid attacks.
Cut back on sugar. Reducing how much sugar you eat—and how often –deprives bacteria of a prime food source. Constant snacking throughout the day on sweets worsens the problem because it prevents saliva, the body's natural acid neutralizer, from reducing high acid levels produced while eating. Constant snacking doesn't allow saliva to complete this process, which normally takes about thirty minutes to an hour. To avoid this scenario, limit any sweets you eat to mealtimes only.
Wait to brush after eating. Although this sounds counterintuitive, your tooth enamel is in a softened state until saliva completes the acid neutralizing process previously described. If you brush immediately after eating you could brush away tiny particles of softened enamel. Instead, rinse your mouth out with water and wait an hour for saliva to do its work before brushing.
Boost your saliva. Inadequate saliva flow could inhibit the fluid's ability to adequately neutralize acid or provide other restorative benefits to tooth enamel. You can improve flow with supplements or medications, or by drinking more water during the day. Products with xylitol, a natural sugar alternative, could give you a double benefit: chewing gums and mints containing it could stimulate more saliva flow and the xylitol itself can inhibit bacterial growth.
Do-it-yourself (DIY) whitening kits are a popular option for restoring a healthy shine to stained and dulled teeth. They're relatively safe and generally live up to their packaging claims.
But a home kit might not always be your best option. Here are 4 reasons why DIY whitening might not be right for you.
You're on the early side of your teen years. Tooth whitening at home is quite popular with teenagers. For older teens it doesn't really pose a dental risk as long as you use the product appropriately (more on that in a moment). However, the immature enamel of younger teens' permanent teeth is still developing and can be vulnerable to damage by whitening processes.
You don't follow instructions well. Not to say you have this particular character quirk — but if you do you may run into trouble with DIY whitening. Home kits are safe if you follow their instructions carefully. If you use them to excess as one 13-year old boy was reported to have done, you could severely (and permanently) erode your teeth's protective enamel.
Your teeth are in need of dental work. Tooth whitening can't fix everything that may be contributing to an unattractive smile. It's always better to have issues like dental disease or chipped teeth addressed first before whitening. And, if your tooth discoloration originates from inside your tooth, a whitening kit won't help — they're only designed for staining on the enamel's outside surface. You'll need a special dental procedure to whiten internal (or intrinsic) tooth staining.
You want to control the amount of brightness. Home kits don't have the level of fine-tuning that a clinical procedure can achieve. While the bleaching agent in a professional whitening solution is much stronger than a home kit, your dentist is trained in techniques that can vary the amount of bleaching, from a softer white to dazzling “Hollywood” bright. And clinical whitening usually takes fewer sessions and may last longer than a home kit.
If you're interested in teeth whitening, see your dentist for a dental examination first before purchasing a DIY kit. Even if you decide to do it yourself, your dentist can give you buying advice for whitening kits, as well as how-to tips.

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.
