I saw it first on my Facebook feed some months ago, something about Glide containing harmful chemicals and not being good to use.
What’s the real story?
It turns out that a study published back in January found compounds called PFAS in the bodies of people who flossed with Glide.
What’s a PFAS?
Per - and polyfluoroalkyl substances – PFAS – are man-made chemicals that repel oil and water. They’re found in things as diverse as non-stick cookware (e.g., Teflon), fast food containers, stain-resistant carpet, weatherproof clothing, and …. Glide floss. They’ve been around since the 1940’s and can accumulate in our bodies and stay around a long time.
Are they harmful?
PFAS, according to https://www.epa.gov/pfas/basic-information-pfas, have been linked to increased cholesterol levels. There are limited findings that they may have immunological, hormonal and reproductive effects also. And one compound, PFOA, has been linked to cancer. Research is ongoing and there is concern because these are “forever chemicals” – they linger in our bodies, in our drinking water, and in the environment. https://www.consumerreports.org/toxic-chemicals-substances/pfas-chemicals-should-you-be-concerned/
The study in question, published in the Journal of Exposure Science and Environmental Epidemiology, measured levels of PFAS in the blood of 178 women and looked at their habits, which in some cases included using Glide. There is no way to know whether the PFAS were there because of flossing, using non-stick fry pans, ordering take-out pizzas, or any other activity. And, more importantly, the study says nothing about the effects these chemical compounds had on the subjects’ health.
Glide was developed to make it easy to slip floss between tight teeth. It does just that. The benefits of flossing are great in stemming inflammation and gum disease. Whether PFAS accumulate in the body because of using Glide is still unproven.
Could you use a different type of PFAS-free floss instead? Yes, absolutely. If your teeth are really tight, there are other alternatives that may still be “slippery” enough to get between your teeth. We can give you samples at the office.
The important thing is to keep flossing.
December 5, 2016 is the date when areas of Santa Clara County will begin receiving fluoridated water.
Here are the zip codes of fully or partially fluoridated water as of December 5, 2016:
94022 94024 94028 94040 94041
94043 94085 94086 94089 94301
94303 94304 94305 94306 95002
95008 95032 95035 95054 95111
95112 95116 95118 95120 95121
95122 95123 95124 95125 95127
95131 95132 95133 95134 95135
95136 95138 95148
Interestingly enough, the Santa Clara Valley Water District (SCVWD) voted to fluoridate its water five years ago, in 2011. It has taken this long to fund and implement the change. Fluoridation for the entire county is expected to be complete by 2020.
Non-fluoridated zip codes:
94087 95013 95014 95020 95030
95037 95046 95050 95051 95053
95070 95110 95113 95117 95119
95126 95128 95129 95130 95139
94550 95023 95033 95140 95141
If you live in an area that will be newly fluoridated, we recommend that you discontinue your children’s fluoride supplements starting in December. (Fluoride drops or fluoride in vitamins are regularly prescribed when drinking water is non-fluoridated.)
Questions? The SCVWD has a great website: http://www.valleywater.org/services/Fluoridation.aspx
Question: Is the water in the South Bay fluoridated?
Answer: It’s complicated.
First, some background info. What’s the big deal about fluoride?
Fluoride has been shown to be a player in the fight against tooth decay (i.e., cavities). Fluoride gives teeth resistance to acid attack from the bacteria in plaque. It also reverses early decay by remineralizing the enamel of your teeth.
Fluoride comes in two forms: topical and ingested. The topicals are toothpastes, mouth rinses and in-office varnish we paint on your teeth. Ingested fluorides are swallowed, like supplements and fluoridated water.
20-40% = the decrease in tooth decay when fluoride is added to a community water supply.
So…….fluoride in your water IS a big deal because it helps you, and everyone else in town, not get cavities. It really works!
Is it safe? Yes. “After 60 years of research and practical experience, the preponderance of scientific evidence indicates…..(fluoride is) both safe and effective”, says the American Dental Association website: http://www.ada.org/~/media/ADA/Member%20Center/FIles/fluoridation_facts.pdf?la=en
Fun fact: The CDC has proclaimed community water fluoridation as one of the ten greatest public health achievements of the 20th century.
Not-so-fun fact: San Jose is the largest city in the US without fluoridated water.
But that is about to change! Stay tuned.
There is an addendum to our previous discussion about pH and bottled water from ourknowledgeable representative from GSK, the company that makes Sensodyne.
Our previous discussion was about flavored water drinks. Now we hear that some plain bottled water that we pay good money for have pH readings that fall in the acidic range. In particular, Dasani (made by Coca Cola) and Aquafina (PepsiCo) have pH’s of 5.5 or less (some websites said 4). Remember that pH’s of 5 and under can be harmful to teeth.
Bottled water in general is tricky. It takes some serious research to find out exactly what is in the water we buy, and the results are not always positive. I’m resolved to continue to use my Nalgene bottle, filled with filtered water from our kitchen sink, and carry it with me through the day.
Our patients are wonderful, and I can say without a doubt that the relationships we have with our “peeps” over many years is the best part of our job.
Here’s an example: A few weeks ago, during a hygiene appointment, I had a lovely chat with my patient about her business of supplying fresh herbs to upscale restaurants. A few days later, what appeared in our office but a flat of gorgeous plants.
It made my day! Thanks to Michelle C. for showing this kindness.
So yes, flossing reigns supreme as the best way to clean the spaces between teeth, but oral irrigators have their place.
First, there are the non-flossing people. At some point you have to concede that a patient does not, perhaps cannot, and/or will never EVER use floss. This is where the Waterpik comes in. Its’ ease of use is highlighted in this video: https://www.youtube.com/watch?v=vmFsdYCiYTc#t=38. We won’t argue the point that
“water flossing” is better than no flossing at all.
Second, there are special situations where a Waterpik can really help. Orthodontics, for one. How difficult it is to floss under wires and around brackets! A Waterpik can clean in nooks and crannies that would otherwise be filled with food and debris. When you invest the time and expense on braces, it’s worth it to spend a little more and buy an irrigator to protect that investment and keep the teeth clean and disease-free during ortho treatment.
You also might want to get an irrigator if you have implants, crowns, or bridgework in your mouth. Implants, especially, which can be difficult to floss around, will benefit from the cleansing that a Waterpik provides. Studies show that irrigation can disrupt bacteria down 6 mm into the pockets around implants and teeth, which can greatly reduce inflammation and keep things healthy.
And then there are those who have recession and many spaces between their teeth. A combined regimen of brushing, flossing, and irrigating can keep these teeth and root surfaces clean, free of the bacterial film that so easily reattaches itself to the rougher exposed roots that those “long in the tooth” have. The irrigator here is an adjunct – an additional step in the home care routine that can have dramatic beneficial effects. We are continually impressed with our patients that floss AND irrigate: they stay healthy long term.
