EPA: Gotta keep ’em separated

The EPA will conduct a public hearing on the proposed pretreatment standards for discharges of pollutants into publicly owned treatment works (POTWs) from certain existing and new dental practices on Monday, November 10,  at 1 p.m. in the William J. Clinton-East Building, Room 1153, 1201 Constitution Avenue, NW, Washington, DC.

According to water.epa.gov, the proposal would require such dentists to comply with requirements for controlling the discharge of dental amalgam pollutants into POTWs. The requirements are based on the best available technology or best available control technology, amalgam separators (SolmeteX® Hg5® Series shown above, available at benco.com) and Best Management Practices.  EPA is also proposing to amend the General Pretreatment Regulations (40 CFR Part 403) to streamline oversight requirements for the dental sector.

“The EPA expects compliance with this proposed rule would cut metal discharge to treatment works, half of it from mercury, by at least 8.8 tons a year. The EPA is also proposing to streamline dental sector oversight requirements to cut implementation and oversight costs of the proposed rule to states and localities by $47 million annually,” reported Donna DominoFeatures Editor at drbicuspid.com

The public hearing will provide an opportunity for oral comments to the Agency on the proposed pretreatment standards.  Typically, each presenter will have three to five minutes to speak.  A transcription of the oral comments will be available on this page following the hearing.  Information on optional pre-registration will be provided can be found at: http://water.epa.gov/scitech/wastetech/guide/dental/


December 22, 2014.  Deadline for public comments to EPA on this proposal.  Please see the Federal Register notice for details.

September 2015. EPA expects to finalize the rule, which under the Clean Water Act, will require dentists to install amalgam separators to help cut discharges of dental amalgam to the environment.


Time travel back to 200-400 AD

One factor that did not contribute to the fall of the Roman Empire: gum disease.

At least that’s what we might infer from a study of skulls at the Natural History Museum led by a King’s College London periodontist.  Experts say the Roman-British population appears to have had far less gum disease than we have today.

Modern habits like smoking, and health issues like diabetes can be damaging to oral health, according to further evidence.

The study, published in the British Dental Journal, examined 303 skulls from a Romano-British burial ground in Poundbury, Dorset for evidence of dental disease. Only 5% of the skulls showed signs of moderate to severe gum disease, compared to today’s population of which around 15-30% of adults have chronic periodontitis.
However many of the Roman skulls showed signs of infections and abscesses, and half had tooth decay.

Professor Francis Hughes from the Dental Institute at King’s College London and lead author of the study said at kcl.ac.uk: “We were very struck by the finding that severe gum disease appeared to be much less common in the Roman British population than in modern humans, despite the fact that they did not use toothbrushes or visit dentists as we do today.”

Theya Molleson, co-author of the study from the Natural History Museum said: “This study shows a major deterioration in oral health between Roman times and modern England. By underlining the probable role of smoking, especially in determining the susceptibility to progressive periodontitis in modern populations, there is a real sign that the disease can be avoided.”

How To Eat Halloween Candy and Not Get Cavities

By Lisa L. Knowles, D.D.S./ Intentional Dental Consulting

There is a trick to eating candy and not getting cavities. I didn’t figure it out until a little too late. My childhood was filled with candy, and my teeth represent my poor sugar choices as a consequence.

As an adult and a dentist, I give you my top tricks on how to avoid getting cavities this Halloween season for your sake and for the kids around you:

  1. Do not buy Halloween candy until at least one week prior to Halloween night. I don’t care if it’s on sale or sitting on an end cap in the grocery store. Don’t buy it. You will have time the week before, and you may possibly pay $5 or $10 more in total for your purchases. But, the price of a filling is around $80 for a single surface cavity. The more candy lying around all month, the easier it is to eat it.
  2. If you do buy Halloween candy prior to the week before Halloween night, stash your candy in your highest cupboard. This will make it difficult to reach and therefore less likely to be eaten early.
  3. If you have children, set limits on the amount of candy eaten per day. And, do not let them keep their candy in their bedrooms until they have demonstrated a strong track record of self-control. One of my colleagues told me one year she informed her kids that any leftover candy would be removed the weekend after Halloween. She found wrappers and sucker sticks everywhere in their bedrooms. They ate ALL of their candy because they did not want it to get thrown out.
  4. If you are going to pitch the excess candy, do it undercover. Tell them to eat their favorites Halloween night (up to a certain maximum—our kids get to eat roughly eight bite-sized pieces), and then help the rest slowly disappear when they are gone—but don’t eat it yourself. Throw it out. My kids never eat it all and end up having Halloween candy for weeks.
  5. Eat your candy with a meal. Cavities thrive in an acidic environment. Sugary sweets are very acidic, and it takes the mouth about 30 minutes to buffer the acidic attack. If you constantly pop in a piece of candy every five or ten minutes, the buffering saliva never gets a chance to bring the mouth back to a neutral zone, or neutral pH. By eating your candy with a meal—or right at the end of a meal–you save your body from having to re-buffer again and again. The mouth takes a dip in acidity, chews and swallows food in an acidic environment, and then recovers. If you eat candy right at the end of a meal, the mouth is already at a lower pH, and it does not have to work as hard one more time. Never-ending candy eating at the end of meal is not good either.
  6. Try not to eat candy/sweets after 7 p.m. if you go to sleep around 10 p.m. or later. On Halloween night, this is pretty difficult. But, for other nights, try to abstain. The saliva works as a protective agent in our mouths. The longer the protectant is in the mouth without further particles, the less likely cavities will form. Additionally, the saliva production slows down when we sleep, so the protective agent disappears. This leaves teeth vulnerable to decay.
  7. Brush and floss before bedtimes. People who skip bedtime brushing and flossing often have more cavities. If particles of sweets are left in the mouth all night, with reduced salivary flow, an opportunity exists for cavities to flourish.
  8. Counteract the low pH in your mouth with fluoridated toothpaste that is not acidic itself. Some toothpastes add whitening agents and chemicals that can make the paste acidic. Buy neutral to high pH toothpastes.
  9. Avoid sticky candies and fruit type snacks. Read this post on fruit snacks for further advice: http://www.huffingtonpost.com/2012/02/28/fruit-chew-snacks-ingredients_n_1304369.html
  10. Avoid sour candies. These candies are typically very acidic and they have sugar added to them. Things that are acidic and sugary are tough on the teeth.
  11. Avoid sticky AND sour combined candies. If I were to prescribe cavities, I would say pop a sticky, sour, chewy candy in your mouth every 15 minutes. I can almost guarantee cavities. Since many kids (and parents) do not floss, guess where the cavities likely begin? Yes, right in between their teeth—right where the chewy, sticky candies lodge each night.
  12. Eat candy in moderation and not every day. This is the hardest one of all. A piece of candy is probably enough for one day. I know…that is harsh. Some people can eat one bag in one day.

So maybe I cannot completely guarantee that you will not get cavities if you follow these 12 tips, but I hope you can at least avoid getting some cavities. There are many other reasons why people get cavities, from malformation of enamel on their teeth to poor salivary flow due to the intake of certain medications. Naturally, visiting your dentist for your check-up visit x-rays within 6-12 months from Halloween is advisable, too. This allows the dentist an opportunity to look for those in between cavities that might have snuggled in while you and your particles of chocolate chewies were sleeping. Better to catch them while they are small, than when they are big and hurting. If cavities do form in your mouth, it’s an oral indicator that something has to change. It’s usually how much and how often sugar and acidic products enter your mouth.

Halloween is often celebrated with candy. It’s a cultural ritual hard to stop. But, how you eat your Halloween candy can be changed. Have a safe and happy Halloween!
