Waiting is part of life for a teenager: waiting to get a driver’s license, to graduate high school or to leave home and stretch their wings. A teenager with lost teeth may also need to wait until they’re older to obtain dental implants.
The reason arises from the differences in how implants and natural teeth attach to the jaw. Although natural teeth may seem rigidly set in the bone, they’re actually held in place by an elastic tissue between them and the bone known as the periodontal ligament. Tiny filaments that attach to the teeth on one side and the bone on the other hold the teeth in place, but also allow the teeth to move gradually in response to mouth changes.
A titanium implant post doesn’t have this relationship with the periodontal ligament — it’s attached directly to the jaw bone. Over time the bone, which has a special affinity with titanium, grows and adheres to it to form a durable bond without an attachment to the periodontal ligament. Because of this the implant can’t move like a natural tooth.
This is extremely important for implant placement because the jaws in particular won’t fully develop in most people until their late teens or early twenties: the upper jaw in particular will tend to grow out and down. Natural teeth accommodate to these changes, but the implant can’t — it will appear to retreat into the jaw. The gum tissues surrounding the implant also won’t conform to the continuing growth and may appear receded.
The best approach is to choose a temporary replacement option until the jaws and other facial bone structures have finished growing. One example is a bonded bridge in which we use a bonding agent to attach a bridge of artificial teeth to teeth on either side of a missing tooth — bonding won’t permanently alter them as with a traditional bridge. Once the jaws have finished growing, we can remove the bonded bridge and install the more permanent implant.
Ask any teenager: waiting can be hard. But with dental implants, waiting until the right time will help ensure the attractive result is a permanent one.

Confused about which toothpaste to buy? You’re not alone — we’re all regularly confronted with multiple choices when we shop.
But you can simplify your decision-making process by first remembering that toothpaste has one main objective: helping to break down and remove dental plaque when you brush. Plaque is a thin film of bacteria and food particles that if you don’t remove through brushing and flossing could trigger tooth decay or periodontal (gum) disease.
Toothpastes contain abrasives and detergents to help make this possible. Abrasives like hydrated silica are gritty substances that work with the mechanical brushing action to loosen plaque. Detergents (usually sodium lauryl sulfate) help loosen and break down particles on your teeth that won’t otherwise dissolve with water alone. The combination of these ingredients and daily brushing action enables you to remove a substantial portion of plaque from your teeth every day.
These ingredients (along with others to retain moisture and bind everything together) are the foundation of any toothpaste. There are other additives, however, that you may also want to consider. The most important is fluoride, a naturally-occurring chemical proven to strengthen enamel against tooth decay. If you’re interested in a brighter smile, you can also look for bleaching agents that may help whiten some enamel staining. And, of course, there are various flavors to suit your taste.
You’ll also want to pay attention to ingredients if you have special concerns. If you have sensitive teeth, your dentist may recommend particular brands that help reduce discomfort. You’ll also want to be on the lookout for ingredients that you may be allergic to like the aforementioned sodium lauryl sulfate or flavors like cinnamon. Be sure to read the ingredients label if you have known issues with certain substances.
And while you’re reading the packaging look for one more thing — the American Dental Association Seal of Approval. This seal means any manufacturer claims for lower occurrences of cavities or other effects by that toothpaste have been independently verified.
It can be overwhelming amid all the product messaging to decide which toothpaste is right for you. But by knowing these basic facts about toothpaste, you can feel more confident choosing the right one to help keep your teeth and gums clean and healthy.

Since their introduction over three decades ago, dental implants have evolved into dentistry’s premier tooth replacement choice. While their primary purpose is to replace missing teeth and rejuvenate a patient’s smile, they’re also regarded for another important benefit: they can slow or stop bone loss accelerated by the loss of teeth.
Like all living tissue, bone has a life cycle. Older bone dissolves and is absorbed by the body, a process called resorption. New bone forms and grows to replace the resorbed bone in response to stimuli occurring within the body. In the jaw, this stimulation comes from the forces the teeth receive when we bite or chew.
When a tooth is lost, however, it no longer transmits these force stimuli to the adjacent bone. This results over time in less new growth to replace resorbed bone, and the overall bone mass shrinks. In fact, about a quarter of the normal bone width will diminish in the first year alone after tooth loss. Other serious problems follow, like gum recession or chewing and speaking difficulties. A person’s appearance may also suffer, because as resorption continues unchecked, the underlying foundational bone will continue to shrink. As more teeth are lost, a decrease in the distance between the nose and chin may result causing the lower third of the face to become smaller in size.
Dental implants can interrupt this process by encouraging bone growth around the implant. Implants are made of “osseophilic” titanium, meaning the metal has a natural affinity with bone. After implantation, bone cells will begin to grow and attach to the titanium post. The enhanced growth stabilizes bone loss by providing stimulation to the bone as teeth once did, thereby maintaining bone levels and minimizing potential effects on the patient’s appearance.
Ironically, too much bone loss could make the installation of implants more difficult, since they require a minimum level of bone mass for anchorage. Receiving an implant as soon as is practical once a tooth is lost will minimize the chances of that occurring — and a better chance of improving bone health overall.
