StopWhiteSpotsBeforeTheyAppearWhileWearingBraces

Braces can be a long, involved process, but gaining a more attractive smile and better oral health is worth it. Sometimes, though, braces can produce unintended short-term consequences.

Brace brackets and wires do the work of moving teeth to better positions. They can, however, hinder the wearer's hygiene efforts to remove plaque, a thin film of bacteria and food particles, from tooth surfaces. Plaque buildup increases the risk of dental disease and other ill effects.

One such effect while you're wearing braces is the formation of tiny spots that look pale and chalky on otherwise smooth and polished enamel. These are white spot lesions (WSLs), where acid has remained for too long on the tooth enamel. They occur because acid-producing bacteria escape removal during brushing and flossing due to the braces hardware.

We want to try to prevent WSLs while wearing braces, and not just because they're unattractive. You're actually looking at enamel erosion, which could lead to cavity development at those weakened spots.

Although difficult for you as a braces wearer, daily brushing and flossing is crucial to WSL prevention. You'll need to take more time to be sure you're reaching all around the wires and brackets. You can improve your effectiveness with special brushes for braces and floss threaders or water irrigators. You can also help keep acid levels low by cutting back on acidic foods and beverages, especially sodas, coffee or spicy foods.

Even if you develop WSLs we can treat them effectively, especially if caught early. One way is by aiding enamel re-mineralization through saliva stimulation (the mouth's acid neutralizer) or applying fluoride to the teeth to strengthen enamel. We can also use caries infiltration, a technique that injects tooth-colored resin below the surface of the lesion. This strengthens the weakened enamel and gives the area the appearance of translucence like normal enamel.

While you're wearing braces, focus diligently on keeping your teeth clean of plaque and keep up your regular cleaning visits with us. If you notice any unusual discolorations or abnormalities, see us as soon as possible. Stopping WSLs from developing will help ensure your teeth are healthy and attractive after the braces come off.

EdenSherandtheLostRetainer

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!

If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.

If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?

As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.

And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!
