Most whitening products contain peroxide as the main ingredient. The problem with peroxide is created by something called a hydroxyl-free radical, a by-product of bleaching that causes damage to the gum--damage that may be permanent. In addition, many whitening toothpastes contain abrasive polishing agents to remove some of the surface layer of your tooth, the part most often stained. But remember, this layer offers your tooth the most protection from infection and a barrier to make teeth less sensitive. I consider that a very well-known brand of whitening mouth rinse should be considered a co-carcinogen and that using the product may increase your risk for oral cancer. Stay clear of products that claim to whiten teeth. [2025] - Ellie Phillips

Use xylitol gum or mints after every meal, snack, and drink to alkalize your mouth and support the development of healthy biofilm. If your gums bleed as you brush them, this is a signal to brush the area more thoroughly, not less, since the improved circulation you will create by brushing will help the swelling go away before any permanent damage happens to your gums. If you have previously noticed bleeding gums but they stopped bleeding, this may not be a good sign. This could signal that gingivitis progressed and became the next stage, which is a painless, nonbleeding, more serious gum problem called periodontal disease. [2018] - Ellie Phillips

If you're fortunate enough to have a seven-figure portfolio, there will be no shortage of salespeople ready to flatter you by offering access to exclusive opportunities available only to "accredited investors." These include hedge funds, private equity, peer-to-peer lending, real estate partnerships and on and on. It's possible that some of these opportunities will go on to deliver outsized returns without undue risk, but you'll likely have to accept high expense, illiquidity and a lack of transparency. You're not sacrificing anything by taking a pass and just sticking to index ETFs. And you're not missing out on anything except disappointment. [2021] - Dan Bortolotti

Antagonist inhibitors such as Dayvigo (lemborexant) and Quviviq (daridorexant) have been approved for treating insomnia, and they appear to be promising. They are, however, quite expensive. One drug that we do find helpful for assisting with sleep is trazodone, a fairly old anti-depressant (approved in 1981) that never really took off. At the doses used to treat depression, 200-300 milligrams per day, it had the unwanted side effect of causing users to fall asleep. That side effect is what we want in a sleep medication, especially if it also improves sleep architecture. We have also had good results with the supplement ashwagandha. [2023] - Peter Attia

Sharp corrections tend more often to retrace 61.8% or 50% of the previous wave, particularly when they occur as wave 2 of an impulse wave, wave B of a larger zigzag, or wave X in a multiple zigzag. Sideways corrections tend more often to retrace 38.2% of the previous impulse wave, particularly when they occur as wave 4. [2001] - Robert Prechter
