While your teeth and gums can take a lot, they still face dangers like dental disease. Your teeth are also affected by aging-related wear and tear.
And, something else could put your teeth at risk: teeth grinding. This is an involuntary habit afflicting one in ten adults in which they grind or clench their teeth, often while they’re asleep. This generates higher than normal biting forces that can cause sore jaw joints, accelerated teeth wear and damage to the ligaments that hold teeth in place. In the worst case, you could eventually lose teeth.
So how do you know you’re grinding your teeth, especially if you’re asleep? You might notice your jaw being unusually sore after you wake up or your jaw muscles feel tired. Your dentist may also notice higher than normal tooth wear during a regular checkup. One of the best indicators, though, might be your sleeping partner or family: Teeth gnashing together can be loud enough to disturb others’ sleep.
In treating adult teeth grinding, it’s best to first determine the underlying cause. One of the most prominent reasons is chronic stress: If you’re under high pressure from situations at work or at home, pent-up stress can vent through physical outlets like teeth grinding. You can manage high stress through relaxation techniques, biofeedback or group therapy, which could in turn reduce teeth grinding.
Teeth grinding could also be related to a sleep disorder, such as problems with shifting between nightly sleep cycles. Certain psychoactive drugs are often associated with teeth grinding too. And, because of alterations in brain chemistry, tobacco users are twice as likely to grind their teeth as non-users. So, receiving treatment for a medical condition or making certain lifestyle changes could help lessen a grinding habit.
Many of these approaches take time to alleviate teeth grinding. For immediate relief, your dentist can create a custom mouthguard you wear while you sleep to reduce the effects of teeth grinding. The guard prevents the upper and lower teeth from making contact while biting down, which reduces the forces against them.
The damage from teeth grinding is often cumulative. If diagnosed early, though, we may be able to stop or minimize the damage before it goes too far.

Besides their life-likeness, implants are also prized for their high success rate. More than ninety-five percent of implants continue to function effectively after ten years.
Implants’ advanced technology explains some of their reliability and longevity—they’re as close to natural teeth as we’re now able to achieve. But their impressive success rate also owes to the detailed protocols that dentists follow to install them. One critical part of these protocols is ensuring a patient has enough bone in their jaw to support and precisely situate the implant for the best functional and aesthetic outcome.
Unfortunately, there are situations where a patient doesn’t have enough bone to achieve a satisfactory result. This often happens if there’s been months or years between losing the tooth and considering an implant. The reason why relates to the nature of bone as living tissue.
Like other cellular tissues in the body, bone has a life cycle: Older, worn-out cells die and are absorbed by the body, and new cells form to replace them. The growth cycle in the jaw receives stimulation from the forces generated when we chew, which travel up through the teeth to the bone.
However, this stimulation stops after tooth loss for the related area of bone, which can slow new bone growth. Over time, the volume and density of the bone around a missing tooth gradually decreases, enough eventually to make an implant impractical.
Insufficient bone volume, though, doesn’t necessarily mean an implant is out of the question. We may be able to address the problem by attempting to regenerate the bone through grafting. This is a procedure in which we insert graft material into the affected area of the jawbone. The graft then becomes a scaffold upon which bone cells can grow. After several months, we may have enough regenerated bone to support an implant.
If there’s been too much bone loss, we may still need to consider another form of restoration. But if we can successfully build up the bone around your missing tooth, this premier restoration for replacing lost teeth could become a reality for you.
Dental amalgam—also known as “silver fillings”—has been used for nearly a hundred years to treat cavities. There are several reasons why this mixture of metals has been the go-to material among dentists: Malleable when first applied, dental amalgam sets up into a durable dental filling that can take years of biting forces. What’s more, it’s stable and compatible with living tissue.
But there’s been growing concern in recent years about the safety of dental amalgam, with even some wondering if they should have existing fillings replaced. The reason: liquid mercury.
Mercury makes up a good portion of dental amalgam’s base mixture, to which other metals like silver, tin or copper are added to it in powder form. This forms a putty that can be easily worked into a prepared cavity. And despite the heightened awareness of the metal’s toxicity to humans, it’s still used in dental amalgam.
The reason why is that there are various forms of mercury and not all are toxic. The form making headlines is known as methylmercury, a compound created when mercury from the environment fuses with organic molecules. The compound builds up in the living tissues of animals, particularly large ocean fish, which have accumulated high concentrations passed up through their food chain.
That’s not what’s used in dental amalgam. Dentists instead use a non-toxic, elemental form of mercury that when set up becomes locked within the amalgam and cannot leach out. Based on various studies, treating cavities with it poses no health risks to humans.
This also means there’s no medical reason for having an existing silver fillings removed. Doing so, though, could cause more harm than good because it could further weaken the remaining tooth structure.
The most viable reason for not getting a dental amalgam filling is cosmetic: The metallic appearance of amalgam could detract from your smile. There are newer, more life-like filling options available. Your dentist, though, may still recommend dental amalgam for its strength and compatibility, especially for back teeth. It’s entirely safe to accept this recommendation.
