You've just finished your daily brushing and flossing. How did you do? Swiping your tongue across your teeth can generally tell you: It's a good sign if it glides smoothly; but if it feels rough and gritty, you better take another run at it.
This "tongue test," however, only gives you a rough idea of how well you're removing plaque, that thin bacterial film on teeth most responsible for dental disease. Plaque, though, can be sneaky, "hiding" in the nooks and crannies on the biting surfaces of teeth, around the gum line and in between teeth.
So, how do you know if you're clearing out any plaque holdouts? An effective way is to use a plaque disclosing agent. This over-the-counter dental product consists of a swab, tablet or solution, which contains a dye that's reactive to plaque.
After brushing and flossing as usual, you apply the solution to your teeth for about 30 seconds. You then take a look in the mirror: Any remaining plaque will be stained a bright color that makes it stand out. There are also agents with two colors of dye, one that stains older plaque and one for newer plaque.
The plaque staining not only helps you see how well you've been brushing and flossing, it can also show you areas in need of improved hygiene. For example, if you notice a scalloped pattern around the gum line, that may mean your brush isn't getting into that area effectively. In this way, you can use a disclosing agent to fine-tune your hygiene.
Repeated use of a disclosing agent is safe, but just remember the dye color can be vivid. It does wear off in a few hours, though, so perhaps schedule it for a day off around the house. You should also avoid swallowing any solution or getting any of it on clothing.
The ultimate test, though, is a thorough dental cleaning with your dentist at least every six months. They can verify whether you've been fairly successful with your brushing and flossing, or if you have room for improvement. If you do use a disclosing agent, you can also discuss that with them in working out better strategies to protect your teeth from tooth decay and gum disease.

Finding out you have a cavity isn't the best of news. But finding out it's a root cavity is even worse: if not treated, the decay can spread more rapidly than a cavity occurring in the tooth's crown surfaces.
Our teeth are basically composed of two parts: the crown, the visible tooth above the gum line, and the roots, the hidden portion beneath the gums. The root in turn fits into a bony socket within the jaw to help hold the tooth in place (along with attached gum ligaments).
A tooth crown is covered by an ultra-hard layer of enamel, which ordinarily protects it from harmful bacteria. But when acid produced by bacteria comes into prolonged contact with enamel, it can soften and erode its mineral content and lead to a cavity.
In contrast to enamel, the roots have a thin layer of material called cementum. Although it offers some protection, it's not at the same performance level as enamel. But roots are also normally covered by the gums, which rounds out their protection.
But what happens when the gums shrink back or recede? This often occurs with gum disease and is more prevalent in older people (and why root cavities are also more common among seniors). The exposed area of the roots with only cementum standing in the way of bacteria and acid becomes more susceptible to cavity formation.
Root cavities can be treated in much the same way as those that occur in the crown. We first remove any decayed tooth structure with a drill and then place a filling. But there's also a scenario in which the cavity is below the gum line: In that case, we may need to gain access to the cavity surgically through the gums.
If you have exposed root areas, we can also treat these with fluoride to strengthen the area against cavity formation. And, as always, prevention is the best treatment: maintain a daily schedule of brushing and flossing and regular dental cleanings to remove bacterial plaque.
Because decay can spread within a tooth, dealing with a root cavity should be done as promptly as possible. But if we diagnose and initiate treatment early, your chances of a good outcome are high.

Nina Parker, the host of Love & Hip Hop for six seasons, is now busy with the new game show Blockbusters and her own talk show The Nina Parker Show. But even with a full plate, she took time recently for some personal care—getting a new smile.
Parker's fans are familiar with her noticeable tooth gap. But a video on TikTok in February changed all that: In the video, she teasingly pulls away a mask she's wearing to reveal her smile—without the gap.
Parker and other celebrities like Madonna, Michael Strahan and David Letterman are not alone. Teeth gaps are a common smile feature, dating back millennia (even in fiction: Chaucer described the Wife of Bath as being "gap-toothed" in The Canterbury Tales).
So, what causes a tooth gap? Actually, a lot of possibilities. The muscle between the teeth (the frenum) may be overly large and pushing the teeth apart. There may be too much room on the jaw, so the teeth spread apart as they develop. It might also have resulted from tongue thrusting or late thumb sucking as a child, influencing the front teeth to develop forward and outward.
A tooth gap can be embarrassing because they're often front and center for all the world to see, but they can also cause oral health problems like complicating oral hygiene and increasing your risk for tooth decay. They can also contribute to misalignment of other teeth.
Fortunately, there are ways to alleviate a gap. One way is to move the teeth closer together with either braces or removable clear aligners. This may be the best approach if the gap is wide and it's contributing to misalignment of other teeth. You may also need surgery to alter the frenum.
You can also reduce less-pronounced gaps cosmetically with dental bonding or porcelain veneers. Bonding involves applying a type of resin material to the teeth on either side of the gap. After some sculpting to make it appear life-like, we harden the material with a curing light. The result is a durable, tooth-like appearance that closes the gap.
A veneer is a thin wafer of porcelain, custom-made to fit an individual patient's tooth. Bonded to the front of teeth, veneers mask various dental flaws like chips, deformed teeth, heavy staining and, yes, mild to moderate tooth gaps. They do require removing a small amount of enamel on the teeth they cover, but the results can be stunning—completely transformed teeth without the gap.
Getting rid of a tooth gap can be a wise move, both for your smile and your health. You may or may not take to social media to show it off like Nina Parker, but you can feel confident to show the world your new, perfect smile.
