In 2016, voters in three states—California, Massachusetts and Nevada—joined Alaska, Colorado, Oregon, Washington and the District of Columbia in legalizing the use of recreational marijuana. These referenda moved the country closer to what may soon be a monumental political showdown between the states and the federal government, which still categorizes marijuana as a controlled substance.
But there’s another angle to this story often overshadowed by the political jousting: is increased marijuana use a good thing for your health and overall physical well-being?
When it comes to your dental health, the answer might be no. The Journal of Periodontology recently published a study that included frequent marijuana users showing increased signs of periodontal (gum) disease. This harmful bacterial infection triggered by plaque buildup can cause weakening of gum attachment to teeth and create the formation of large voids between teeth and gums called periodontal pockets. Left untreated, the disease can also cause supporting bone loss and eventually tooth loss.
The study looked at the dental treatment data of over 1,900 adults of which around one-quarter used marijuana once a month for at least a year. Marijuana users in the study on average had 24.5% of pocket sites around their teeth with depths of at least eight millimeters (an indication of advanced gum disease). In contrast, non-users averaged around 18.9% sites.
To be sure, there are several risk factors for gum disease like genetics, oral hygiene (or lack thereof), structural problems like poor tooth position or even systemic conditions elsewhere in the body. This published study only poses the possibility that marijuana use could be a risk factor for gum disease that should be taken seriously. It’s worth asking the question of whether using marijuana may not be good for your teeth and gums.
Orthodontics can produce an amazing smile transformation. With today’s advanced appliances and techniques even the most difficult malocclusions (bad bites) can be overcome. All of this innovation, however, depends on one basic anatomical fact: though firmly set in the mouth, our teeth can still move.
Teeth are actually held in place by the periodontal ligament, a strong, elastic tissue that attaches to them through tiny collagen fibers on one side of the ligament and to the jawbone with similar fibers on the other side. When pressure is placed against a tooth, the bone on the opposite side of the force begins to dissolve (resorb), allowing the tooth to move. As it moves, new bone is built up behind the tooth, to stabilize it. Orthodontists take advantage of this natural mechanism through orthodontic hardware like braces that applies pressure in the desired direction of movement, while the ligament and bone do the rest.
There is, though, a downside to this process. The teeth, bone and gum tissues can contain a kind of “memory” for the former natural position of the teeth. Over time, the lower front teeth tend to take a gradual migratory movement back towards their original position. Also, as we age the lower front teeth may crowd each other as there is a genetic influence for teeth to move to the midline of the face, causing a pressure that allows the skinny lower front teeth to slip behind each other. As a result of both of these tendencies, corrected teeth may retreat from their new positions.
To stop these tendencies, we use an appliance known as a retainer after braces or other hardware is removed. As the name implies, this appliance “retains” the teeth in their new position. For structural “memory,” the retainer will keep the teeth in their new position until the impulse to return to the old one has faded, about eighteen months. Retainers can also slow or stop the natural genetic influence of movement, but it may mean wearing a retainer for an indefinite period, especially individuals who’ve undergone orthodontic treatment later in life.
The length of time you’ll need to wear a retainer after braces — and what type, whether a removable appliance or one permanently attached — will depend on a number of factors including the type of malocclusion, your individual mouth structure and age. We’ll recommend the best option that ensures the best chance of keeping your teeth in their new position.

Cavities can happen even before a baby has his first piece of candy. This was the difficult lesson actor David Ramsey of the TV shows Arrow and Dexter learned when his son DJ’s teeth were first emerging.
“His first teeth came in weak,” Ramsey recalled in a recent interview. “They had brown spots on them and they were brittle.” Those brown spots, he said, quickly turned into cavities. How did this happen?
Ramsey said DJ’s dentist suspected it had to do with the child’s feedings — not what he was being fed but how. DJ was often nursed to sleep, “so there were pools of breast milk that he could go to sleep with in his mouth,” Ramsey explained.
While breastfeeding offers an infant many health benefits, problems can occur when the natural sugars in breast milk are left in contact with teeth for long periods. Sugar feeds decay-causing oral bacteria, and these bacteria in turn release tooth-eroding acids. The softer teeth of a young child are particularly vulnerable to these acids; the end result can be tooth decay.
This condition, technically known as “early child caries,” is referred to in laymen’s terms as “baby bottle tooth decay.” However, it can result from nighttime feedings by bottle or breast. The best way to prevent this problem is to avoid nursing babies to sleep at night once they reach the teething stage; a bottle-fed baby should not be allowed to fall asleep with anything but water in their bottle or “sippy cup.”
Here are some other basics of infant dental care that every parent should know:
- Wipe your baby’s newly emerging teeth with a clean, moist washcloth after feedings.
- Brush teeth that have completely grown in with a soft-bristled, child-size toothbrush and a smear of fluoride toothpaste no bigger than a grain of rice.
- Start regular dental checkups by the first birthday.
Fortunately, Ramsey reports that his son is doing very well after an extended period of professional dental treatments and parental vigilance.
“It took a number of months, but his teeth are much, much better,” he said. “Right now we’re still helping him and we’re still really on top of the teeth situation.”
