When a device meant to make your life easier doesn't function properly, it can be extremely frustrating. This is sometimes the case for people who wear lower dentures, which loosen over time. These removable replacement teeth can become less reliable and more uncomfortable. Why does this happen?

The answer is bone loss. When a tooth is lost, the bone surrounding it deteriorates and this will change the shape of the jawbone in your mouth. You may find that a lower denture that once had a snug fit on your lower jaw is now sliding around. This happens more often on the bottom because your muscular tongue pushes against the denture. Also, a top denture has more surface area due to an artificial palate to help create suction to the roof of the mouth and keep it in place.

Dental implants, which permanently replace the roots of teeth, do not loosen and they also prevent bone loss. But replacing a whole set of bottom teeth with dental implants and crowns is expensive. What to do?

There's a relatively new solution that combines the security of implants with the affordability of a removable denture. It's called an overdenture, and it may be something you want to consider. An overdenture is a lot like the removable lower denture you already have, only it fits over two implants strategically placed in your lower jaw. While the lower denture is still removable, its stability is greatly improved.

Studies have shown that people with two-implant overdentures have a higher quality of life, and receive better nutrition, than those wearing conventional dentures. It's not hard to figure out why: A more stable denture makes it easier to eat healthy foods such as vegetables — or, really, any foods — and prevents embarrassing slippage of false teeth.

Dental implants are in much demand when it comes to replacing missing teeth. And although they have long-term success rates of well over 95% when properly placed, the dental profession's current rule-of-thumb is to not use them as a treatment option for teenagers because jaw and facial growth are not complete.

As with most things in life, timing can be everything. However, having missing teeth as a teen can contribute to significant loss of self-esteem and psychological issues. All this means is that we must review each patient's needs on a case-by-case basis so that we can determine the optimal time to place implants while maintaining your teen's self-esteem. However, the good news is that there are some temporary tooth replacements available until the timing is right for implants.

Unlike natural teeth, which move and change position along with normal growth and jaw development, implants don't. Because implants replace tooth roots by fusing with the jawbone, their position is fixed. If placed before normal jaw growth and maturity are complete, they appear to sink as the jaws grow and leave them behind!

Given the above details, you can clearly see why it is critical for jaw and facial growth to be complete prior to placing a dental implant. To determine this timeline, we will work with our dental team, which include orthodontists (specialist in the study of the growth, development and moving teeth into the right positions). Working together, we will best be able to assess when the time is right to plan and place dental implants — usually around late teens.
