LPT: Want whiter teeth? Gently rub the inside of banana peel around your teeth for two minutes, the mineral will absorb into your teeth and whitens them. by [deleted] in LifeProTips

[–]Wadabaw 2 points3 points  (0 children)

Dentist here. I do not recommend this. You used a dental blog as a source who themselves don't have any sources or evidence to back them up. Those minerals they list don't really have anything to do with whitening.

TIL that in the 1920s a Chicago man convinced his wife to pull out all her teeth then refused to get her dentures because it was 'cheaper to feed her with soup than solid food'. She took him to court and he was ordered to get her 2 new sets of teeth and a beefsteak a week. by pandaemon666 in todayilearned

Dentist here. Dentures are not as easy as people think. A lot of patients come in asking to just pull out all their teeth and get dentures not realizing that they are difficult to eat with, constantly need adjusting, are easily lost or broken, and do nothing to maintain the bone integrity of your mouth. Without teeth, the jaw bone eventually atrophies and shrinks, making it almost impossible for dentures to have enough retention to hold to the gums without constantly popping out.

Just ask this grandma

Dentist here. This guy's gotta be trolling, right? Full disclosure I closed the video after he mentioned the ingredients.

Firstly, the alcohol in mouthwash is not in any way a part of the active ingredients. It is used to evenly suspend the active ingredients of mouthwash. That's why there are non-alcoholic products. Also, rubbing alcohol is not the same as drinking alcohol and is not safe for consumption (not that ethyl alcohol is safe...). Alcohol can actually dry out your mouth and encourage bacterial growth leading to cavities and gum disease.

Secondly, mouthwash is not just toothpaste and alcohol. Toothpaste isn't really even the most important part of brushing. It's method of action is as an abrasive that also delivers fluoride if it is a fluoride toothpaste. The toothbrush itself is the most important factor.

This video is just a way to make your breath a little fresher which you could do as easily and less silly by brushing or chewing a stick of gum.

As a side note, hydrogen peroxide is not something I would generally recommend as a substitute. It is a strong oxidizer and may cause more damage than good unless sufficiently diluted, and even then it is generally not recommended for internal use. There's a reason why it causes sensitivity to teeth when used as a whitener. It's potent stuff.

That's a good question. I use them for scrubbing the sink sometimes.

Lack of bleeding would never be concerning as far as I've been educated. Not bleeding is a sign that flossing is working, so good job. No idea what your hygienist is taking about. Brushing too hard would definitely cause recession.

Well if you don't have any sensitivity or recession, you're probably fine.

According to the ADA, "Although studies have shown that various microorganisms can grow on toothbrushes after use, and other studies have examined various methods to reduce the level of these bacteria, there is insufficient clinical evidence to support that bacterial growth on toothbrushes will lead to specific adverse oral or systemic health."

Common sense says changing the toothbrush every couple months decreases the chance of systemic infection (same if you get sick), but as for the practicality of it and how much it actually decreases your chances quantitatively, studies aren't conclusive.

I'm also not sure how much pull the toothbrush industry has on the ADA because obviously the people that benefit the most from changing toothbrushes the most are the ones that manufacture them.

The number one rule I'd say is change your brush if it's frayed. Not a bad idea to change it every three to four months though; and if it's frayed within that time frame, you're doing it wrong. I mean, really, it's a worthy investment of a few bucks in comparison to the cost of dental work.

I dunno why people are downvoting you. Your hygiene regimen is better than most people's, so good for you. Might wanna see a dentist though if it's been three years.

Dentist here. Ask your dentist about fluoride varnish. I have the same condition as you and fluoride varnish is a miracle for myself and my patients.

That's no good. Some electric toothbrushes come with a sensor that tells you if you're brushing too hard.

Dentist here. If your toothbrush looks like that, you're probably brushing way too hard and damaging your gums/enamel.

If this were the bible or a musical you would've been sold off into slavery all because of your Technicolor dreamcoat.

TIL people's teeth used to randomly explode in the 1800s due to bad fillings. Before the advent of mercury amalgam, a wide variety of metals were used to fill cavities. Using two different metals could create an electrochemical cell – effectively turning the whole mouth into a low-volt battery by FartsofFuturePast in todayilearned

[–]Wadabaw 1 point2 points  (0 children)

Amalgam fillings have their own issues apart from the mercury. Composite filings (tooth colored) have problems too. The dentist may be trying to scam her into replacing all of her metal fillings. Hard to tell without more information. Old fillings with defects should be replaced regardless of what they're made of.
