It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

During his former career as a professional footballer (that's a soccer star to U.S. sports fans) David Beckham was known for his skill at “bending” a soccer ball. His ability to make the ball curve in mid-flight — to avoid a defender or score a goal — led scores of kids to try to “bend it like Beckham.” But just recently, while enjoying a vacation in Canada with his family, “Becks” tried snowboarding for the first time — and in the process, broke one of his front teeth.
Some fans worried that the missing tooth could be a “red card” for Beckham's current modeling career… but fortunately, he headed straight to the dental office as soon as he arrived back in England. Exactly what kind of treatment is needed for a broken tooth? It all depends where the break is and how badly the tooth is damaged.
For a minor crack or chip, cosmetic bonding may offer a quick and effective solution. In this procedure, a composite resin, in a color custom-made to match the tooth, is applied in liquid form and cured (hardened) with a special light. Several layers of bonding material can be applied to re-construct a larger area of missing tooth, and chips that have been saved can sometimes be reattached as well.
When more tooth structure is missing, dental veneers may be the preferred restorative option. Veneers are wafer-thin shells that are bonded to the front surface of the teeth. They can not only correct small chips or cracks, but can also improve the color, spacing, and shape of your teeth.
But if the damage exposes the soft inner pulp of the tooth, root canal treatment will be needed to save the tooth. In this procedure, the inflamed or infected pulp tissue is removed and the tooth sealed against re-infection; if a root canal is not done when needed, the tooth will have an increased risk for extraction in the future. Following a root canal, a tooth is often restored with a crown (cap), which can look good and function well for many years.
Sometimes, a tooth may be knocked completely out of its socket; or, a severely damaged tooth may need to be extracted (removed). In either situation, the best option for restoration is a dental implant. Here, a tiny screw-like device made of titanium metal is inserted into the jaw bone in a minor surgical procedure. Over time, it fuses with the living bone to form a solid anchorage. A lifelike crown is attached, which provides aesthetic appeal and full function for the replacement tooth.
So how's Beckham holding up? According to sources, “David is a trooper and didn't make a fuss. He took it all in his stride." Maybe next time he hits the slopes, he'll heed the advice of dental experts and wear a custom-made mouthguard…

If you’re in the initial planning stages for a dental implant, you may already be encountering a number of options to consider. One that may come up is how the visible crown will attach to the metal implant imbedded in the bone.
Generally speaking, implants are composed of two parts: a metal post most often made of titanium placed into the bone that serves as the “root” for the new tooth; and a visible, life-like crown made of dental porcelain that attaches to an abutment on the titanium post. The crown can be attached in one of two ways: either with a small screw through the biting surface of the crown into a receiving hole in the abutment or cemented to it.
The major advantage of a screwed crown is that it allows for easy removal of the crown if needed. While the titanium post can often last a lifetime, porcelain crowns more often need repair or replacement since they receive the brunt of the biting forces in the mouth. A screw-attached crown is much easier to remove than a cemented one.
On the other hand, screwed crowns have a small access hole that must be restored with a tooth-colored filling to help the crown appear natural. This isn’t too great an issue with back teeth but does make achieving a natural appearance in the front more difficult. Cemented crowns look more like a natural tooth and are thus more flexible in achieving the desired appearance.
Besides the possibility the cement may cause gum inflammation or bone loss, the chief detraction from cemented crowns is the difficulty in removing them. Crowns are often damaged in this process so it’s highly likely it will have to be replaced rather than repaired. It’s possible to use weaker cement, but this raises the risk of the crown coming loose at some point from the abutment.
As we plan for your implant, we’ll discuss which type of attachment will work best for you, depending on the tooth to be replaced and other conditions with your oral health. The end result, though, should be the same — a new, natural-looking tooth that serves you well for many years to come.

There are a number of ways to improve unsightly teeth. You can, of course, replace them with dental implants — but not if they're still viable. You can crown them: however, you'll have to significantly reduce their structure for the crowns to fit over them.
There is another less invasive option for teeth with mild to moderate imperfections — you can cover them with porcelain veneers. As the name implies, a veneer is a thin covering of dental porcelain bonded to the outside surface of a tooth. They literally put a “new face” on chipped, stained or slightly gapped teeth.
You'll first need a dental examination to ensure your teeth are reasonably healthy and that you don't have any significant dental problems that could interfere with the veneers. We can then design your veneers' shape and color to achieve the look you desire. We can also create a temporary “trial smile” with acrylic replicas of your proposed veneers to give you a realistic impression of your future smile.
The next step is the possibility the teeth need to be prepared for the veneers. Although quite thin, veneers can still make the teeth look larger or bulky. To compensate, we remove some of the tooth enamel. Although much less than for a crown, this alteration is still permanent: your teeth will need some form of restoration from now on. There are also “no-prep” veneers, which require no tooth surface reduction.Â Ask us if this is an option.
We then make an impression of the teeth, which with other information will guide a technician at a dental laboratory to manually create your new veneers. This can take several weeks and requires a high degree of artistry to produce a custom product that will match your teeth.
Once they've arrived, we'll use a permanent bonding process to precisely attach them to your teeth.Â It will then be up to you to care for your veneers, especially not biting down on anything hard that could chip or crack them. You should also maintain regular dental visits and proper oral hygiene to keep your smile as bright and attractive as possible.
Although small in size, veneers can make a big impression. They can restore the smile you once had — or give you the look you've always wanted.

A toothache means you have tooth decay, right? Not necessarily — your pain could be signaling a number of potential causes. Determining where, how much and how often it hurts will help us find out the cause and apply the appropriate treatment.
A single symptom, for example, can mean many things. A twinge of tooth pain as you consume hot or cold foods might indicate localized tooth decay easily repaired by a filling. But it could also mean the tooth's root surface has been exposed as a result of periodontal (gum) disease — aggressive plaque removal and maybe even gum surgery might be necessary. Or it could be a sign of inner pulp decay: in this case you'll likely need a root canal treatment to save the tooth.
Pulp decay can also announce itself with a very sharp and constant pain radiating from one or more teeth. You shouldn't hesitate to see us for an examination — even if the pain goes away. Pain cessation most likely means the nerves in the pulp have died. The infection, however, still exists, so you'll still probably need a root canal treatment.
If you notice severe, continuous pain and pressure around a tooth, particularly about the gums, you may have a localized, inflamed area of infection called an abscess. An abscess can be the result of gum disease, but it might also stem from a foreign body like a popcorn husk, getting stuck below the gums. We'll need to conduct a complete dental examination to determine the cause and how to treat it.
Finally, a sharp pain when you bite down could mean many things such as a loose filling or a fractured (cracked) tooth. The latter especially requires immediate attention to save the tooth.
These are just a few of the possible causes behind mouth or facial pain. Although all of them are serious, a few are true dental emergencies and can't wait if we're going to save a tooth. The sooner you see us, the sooner we can help relieve the pain, minimize any damage and avert disaster.
