Besides attractively showcasing your teeth, your gums protect your teeth and underlying bone from bacteria and abrasive food particles. Sometimes, though, the gums can pull back or recede from the teeth, leaving them exposed and vulnerable to damage and disease.
Here are 4 things that could contribute to gum recession—and what you can do about them.
Periodontal (gum) disease. This family of aggressive gum infections is by far the most common cause for recession. Triggered mainly by bacterial plaque, gum disease can cause the gums to detach and then recede from the teeth. To prevent gum disease, you should practice daily brushing and flossing and see your dentist at least twice a year to thoroughly remove plaque. And see your dentist as soon as possible for diagnosis and treatment at the first sign of red, swollen or bleeding gums.
Tooth position. While a tooth normally erupts surrounded by bone, sometimes it erupts out of correct alignment and is therefore outside the bony housing and protective gum tissue. Orthodontic treatment to move teeth to better positions can correct this problem, as well as stimulate the gum tissues around the involved teeth to thicken and become more resistant to recession.
Thin gum tissues. Thin gum tissues, a quality you inherit from your parents, are more susceptible to wear and tear and so more likely to recede. If you have thin gum tissues you'll need to stay on high alert for any signs of disease or problems. And you should also be mindful of our next common cause, which is….
Overaggressive hygiene. While it seems counterintuitive, brushing doesn't require a lot of "elbow grease" to remove plaque. A gentle scrubbing motion over all your tooth surfaces is usually sufficient. On the other hand, applying too much force (or brushing too often) can damage your gums over time and cause them to recede. And as we alluded to before, this is especially problematic for people with thinner gum tissues. So brush gently but thoroughly to protect your gums.

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.

For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.
