We do know that (at least one of) his dentures used human teeth, as you can see in this picture of the exhibit (taken from Snopes), which says: Contrary to popular myth, Washington’s false teeth were not made of wood but of human and cow teeth as well as elephant ivory. In addition, the official website of Mount Vernon notes that: Washington bought human ...

There are only three studies in PubMed that mention CrissCross bristle design explicitly. The first, authored by Oral-B Laboratories, finds that "comparisons with more than 80 leading manual toothbrushes from around the world demonstrate a consistent, significant advantage for the new CrossAction toothbrush, both with respect to interproximal penetration ...

A journal article on the topic found a negligible (but non-zero) effect of carbonated waters on tooth enamel. The claim in the Daily Mail is clearly in dissonance with the results from this study. Dissolution levels with all of the mineral waters were very low and for several still waters were undetectable. (...) De-gassing of a sparkling mineral water ...

While it's a bad idea to put fragile glass objects in your mouth, the primary assertion here is clearly false. First of all, there are at least five different YouTube videos where people try it out and have no problems. Here is one that includes various sizes and shapes. Secondly, if this were possible, it is likely that cases would appear in the medical ...

That's an interesting question! So I will first explain the exact mechanism of Xylitol in our oral cavity. Xylitol, is a naturally occurring five-carbon sugar polyol, a white crystalline carbohydrate. Now the most significant contributor or the pioneer bacteria for dental caries (which further leads to tooth decay) is Streptococcus Mutans. Xylitol reduces ...

Bottom line: It doesn't matter if you floss before or after brushing your teeth. This question has been debated endlessly within the dental community. On this site it is really hard to conclude which one is better due to many different papers like you cited and many different points of views from dentists and professionals. I will cite one answer only ...

Dental X-rays are not 100% free of risk. However, they are very, very low risk. Given people take risks with radiation every day (going into the sun, eating bananas), it is reasonable to accept the risks of dental X-rays to gain the health benefits associated with their diagnostic abilities. This xkcd info-graphic puts the risk in perspective - click to ...

According them them, their 4 essential oils are Eucalyptol Menthol Methyl salicylate Thymol Menthol, Thymol and Eucalyptol do have known antibacterial effects. I'm having difficulty finding anything specifically on Methyl salicylate (wintergreen oil), but their claims of efficacy against plaque seem plausible. Additionally, a Japanese study comparing ...

Summary: A. Using fluoridated toothpaste in both children and adults reduces the risk of dental caries. B. Fluoridated toothpaste increases the risk of dental fluorosis only when children 8 years old or younger swallow it, in which case fluoride is absorbed, enters the blood and from there the teeth. Fluoride in children in adults does not enter the teeth ...

It won't prevent, it can reduce the harm of drinking soda, but only in a specific usage, which is not the common one, using a straw in the "wrong" way would cause more damage to the teeth. The article in question cites the article Influence of drinking patterns of carbonated beverages on dental erosion which reviews two case studies of teens (16 ...

There is significant discussion of this issue in Fluoride in Drinking Water: Scientific Review of EPA's Standards (2006), particularly in chapter 8, Effects on the Endocrine System. This book is a publication of the US National Research Council. As with other calcifying tissues, the pineal gland can accumulate fluoride (Luke 1997, 2001). Fluoride has ...

Answer: Yes, it probably does. I found this referenced answer on authoritynutrition.com. The catechins in green tea have other biological effects as well. Some studies show that they can kill bacteria and inhibit viruses like the influenza virus, potentially lowering your risk of infections (31, 32, 33, 34). Streptococcus mutans is the primary harmful ...

If brushing your teeth with traces of acid in your mouth really is dangerous, shouldn't we hear about it without mentioning of vomit? Yes, and we do (from Colgate): You should know, however, that brushing your teeth after eating can sometimes affect your tooth enamel. According to the Mayo Clinic, if you've consumed anything acidic, you should avoid ...

It's important to begin by discussing the mechanism that drives tooth decay: Chapter 99 – Microbiology of Dental Decay and Periodontal Disease. Loesche. Medical Microbiology. 1996. Dental decay is due to the irreversible solubilization of tooth mineral by acid produced by certain bacteria that adhere to the tooth surface in bacterial communities ...

Mew's orthotropics are considered fringe or pseudoscience because they lack the standard scientific support such as randomized controlled trials. Sir, I was bemused to find myself reading the book review of J. Mew's book in the 9 May edition of the BDJ (216: 493) whilst the radio news announced another controversy regarding the publication of controversial ...

Effects of coconut oil on oral health: A 2016 study showed coconut oil pulling to be a safe and effective alternative to Chlorhexidine mouthwash since there was a significant reduction in Streptococcus mutans count. Conclusion: Oil pulling can be explored as a safe and effective alternative to Chlorhexidine. Clinical significance: Edible oil-pulling ...

There is no genuine proof that those golden/silver crowns were not put in by dentists. It is quite common in dentistry to restore a missing or carious tooth by a gold crown or a gold restoration. Also according to the article God and the Golden Teeth: One pastor peeled back his lip to show reporters a glittering gold crown, which he claimed had miraculously ...

Such statements are not to be intended in the "scientific" sense. They are marketing materials and are not claimed to be representative of all dentists. Stock phrases such as "Recommended by nine out of ten dentists" in commercials for non-prescription consumer healthcare products such as Sensodyne toothpaste are devised by the parent company's Global ...

In this answer, "diet soda" refers to any sugar-free version of the drinks known as soda. "In many parts of the U.S., soda is a sweet, fizzy drink (Vocabulary.com)." Is diet soda as bad for your teeth as regular soda? According to some experiemental studies, diet soda can be erosive to teeth, but seems to be less erosive than regular soda. An in vitro ...

The ADA's stance is overly diplomatic because it is a political entity and not a scientific resource so I wouldn't expect them to provide productive clinical guidance one way or another. Creating well controlled longitudinal studies with a sufficient sample size to evaluate the clinical benefit of a particular oral hygiene regimen is unreasonable and never ...

There is little to no evidence supporting the claim that regular tongue scraping improves anything except bad breath and oral hygiene; however, very little research has been done to credit or discredit such treatment. Let's examine the talking point in her article, 5 Reasons Why Everyone Needs A Tongue Scraper: You want to boost your immunity. Notice ...

Yes, it can, but it's definitely not a magic bullet, or any major innovation. It's also not by some chemical reaction as some people assume. Baking soda is a mild abrasive which is ideal in toothpaste because it's compatible with fluoride, it's not too abrasive as to damage teeth, it's cheap to produce and it's safe to use. How does it whiten the teeth? ...

I believe that if the claim is tweaked slightly, there is some evidence to support it. Originally it says "born without wisdom teeth", which to me sounds like they are missing all of their wisdom teeth. I haven't seen any studies that show that high a rate for that. Also, I believe everybody is "born" without them, since they generally don't start forming ...

The main benefit from flossing appears to be to reduce gingivitis or gum inflammation. Presumably it does this by removing food from the interdental spaces because there is only weak evidence it removes plaque which might be causing gingivitis. This Cochrane review concludes [1] AUTHORS' CONCLUSIONS: There is some evidence from twelve studies that ...

Commercial toothpastes contain fluoride. Home-made ones don't. Fluoride effect on cavity reduction is well-established. For example: https://www.ncbi.nlm.nih.gov/m/pubmed/16208382/ As such, your home-made recipe will either be -less effective (lacking fluorides) -dangerous (if you were silly enough to mix fluorides at home) Going under the assumption ...
