Due to financial circumstances, people often have a lost tooth restored with a removable partial denture, an effective appliance that restores function and a degree of aesthetic appearance. Later, though, they may want to improve both function and appearance with a dental implant.
If this describes you, you’re making a great choice. Dental implants are the closest technology we have to a natural tooth. But there may be a roadblock to your implant, especially if a long time has passed since your tooth loss—there may not be enough bone at the site to place an implant.
The heart of an implant is a titanium metal post surgically imbedded in the jawbone. The titanium naturally attracts bone cells, which grow and adhere to it to form a solid hold that can support a porcelain crown or other restorations like bridges or dentures. But to achieve a natural appearance it’s important that the implant is placed in the right location. To achieve that requires adequate bone.
But there may not be adequate bone if the tooth has been missing for a while. The forces generated when we chew travel through the teeth to the jawbone, which stimulates bone growth. If that stimulus is absent because of a missing tooth, new bone cells may not replace older ones at a healthy rate and the total bone volume begins to diminish. A denture can’t compensate and, in fact, accelerates bone loss.
But there may be a solution: bone grafting. With this procedure we place a donor bone graft into the area of bone deficiency some time before implant surgery. The graft serves as a scaffold for new bone cells to grow upon. Hopefully, this will produce enough healthy bone to support an implant. If the bone deficiency is minor, we may place the implant and the bone graft at the same time.
If you have experienced bone loss, we must first determine the amount of bone at the missing tooth site and whether grafting is a viable option. Bone grafting postpones your implant, but the delay will be worth the wait if we’re successful. With increased bone volume you’ll be able to obtain a new tooth that’s superior to your current restoration.
Visiting the dentist for cleanings, checkups and needed dental work is one of the pillars of dental health, along with daily hygiene and a nutritious diet. But an estimated 50% of people have some form of anxiety about dental visits — and around 15% actually avoid care because of it.
If you feel nervous about dental visits, there are ways to reduce your anxiety. First and foremost is to find a compassionate provider you trust and feel comfortable around, who listens non-judgmentally to your concerns.
But that's only the beginning: depending on your degree of anxiety, you could require more help to relax through sedation medication. The drugs and methods used can induce various degrees of consciousness ranging from mild relaxation to more sleep-like states.
The most basic is oral sedation. Typically, this involves taking the medication by mouth about an hour before an appointment. You can take it by itself to increase relaxation or along with other forms of sedation (like inhaling nitrous oxide gas) or local anesthesia.
Beyond inhalation, a higher level of sedation involves injecting the medication into the blood stream through an intravenous (IV) drip. This induces a deeper “semi-awake” level of consciousness, but differs from general anesthesia, which places a patient into unconsciousness to block pain during a major procedure. With IV sedation you may still be able to respond to verbal commands or touch; and although you're monitored for vital signs you won't need medical assistance to maintain breathing and heart function.
With today's advanced sedation drugs and methods, we can control dosages to achieve just the right level of sedation, as well as reduce the amount of time the drug may affect you afterward in recovery. Many drugs also have an amnesiac effect so that you'll remember little if any about the procedure afterward.
Whether by mouth, inhalation or with an IV, sedation therapy can make a difference no matter what your level of anxiety. And if your dental visits continue to be comfortable and pleasant ones, you're more likely to receive the care you need to keep your teeth and gums healthy.

As dentists, we often see other mouth problems besides those with teeth and gums. One of the most common is cracking around the corners of the mouth. Although usually not serious, it can be irritating and uncomfortable.
Medically known as angular cheilitis (literally “an inflammation of the angles of the lip”), it’s also called perleche, derived from the French lecher, “to lick.” The latter moniker aptly describes the tendency of sufferers to compulsively lick the sores to relieve irritation, which actually can make things worse.
Perleche has a number of possible causes, mostly from in or around the mouth (although systemic diseases or medications can cause it on rare occasions). It’s often found among younger people who drool during sleep or older people with deep wrinkles along the sides of the mouth that increase the chances of dryness and cracking. Long-term wind or cold exposure, ill-fitting dentures or a lack of back teeth (which help support facial structure) may also contribute to the condition.
Patients with perleche can also develop yeast infections from a strain called candida albicans. The infection can spread through the whole mouth, significantly increasing the chances of physical discomfort.
Treating perleche often involves topical ointments with inflammation-reducing steroids and zinc oxide, which has antifungal properties, to provide an environmental barrier during the healing process. If a yeast infection occurs, we may treat it with oral or topical antifungal medication like Nystatin for the whole mouth and chlorhexidine rinses, which has antibacterial properties.
It also helps to adopt a few preventive measures that can minimize the occurrence of perleche. If you wear dentures, for example, cleaning them often (including, if necessary, with chlorhexidine) and leaving them out at night reduces bacterial and fungal growth. We can also see if your dentures are fitting properly. Replacing missing teeth provides better facial support and could minimize wrinkling around the mouth. And, of course, keeping up daily brushing and flossing helps ensure a healthy and disease-free mouth.
If you’re experiencing cracked mouth corners, let us know at your next appointment. With our help and of other medical professionals we may be able to give you relief from this irritating condition.
