Dentists Reveal the Number-1 Reason Your Teeth Aren't as White as They Used to Be
Think of your favorite photos. You're likely doing something unforgettable or are surrounded by the people you love the most and everybody is smiling. Now think about one that you took more recently. Does your smile look a bit duller or a little more yellow? If it does, you're not alone. As you get older, the outer layer of your teeth (the enamel) gradually thins, exposing more of the next layer (the dentin), which is naturally yellow, according to the Cleveland Clinic. And to make matters worse, there are everyday habits that can speed up this process. Meet the experts: Harold Katz, D.D.S., founder of The California Breath Clinics and creator of Therabreath; Katia Friedman, D.D.S., co-founder of Friedman Dental Group in Florida; Mazen Natour, D.M.D., a Manhattan-based prosthodontist. The good news: There are some changes you can make to keep enamel stronger and prevent that dentin from peeking through—as well as reduce the food stains that can make teeth appear lackluster as well. Here are some yellow teeth habits to switch up. You're rinsing with mouthwash too often. One of the toughest environments for your teeth is a dry mouth, said dentist Harold Katz, D.D.S., founder of The California Breath Clinics and creator of Therabreath, a line of oral care products. That's because saliva has a combination of minerals, enzymes, and oxygen compounds that keep the pH balance in your mouth neutral—reducing the acid that can wear away enamel. Saliva also bathes the teeth regularly to knock out bacteria and to prevent stains from adhering to enamel. 'What is disheartening is that many commercial mouthwashes are very acidic, and if used very frequently, may destroy precious tooth enamel,' said Dr. Katz. Indeed, a study in the Journal of Oral Science found that people who used mouthwash for 12 weeks had more enamel loss and tooth color change over that time than a control group. So, if you're taking frequent swigs of mouthwash to keep breath fresh, you may want to consider other strategies, like brushing more frequently and getting regular dental cleanings. You're consuming a lot of acidic fruits, vegetables, and drinks. Just as more acidic mouthwash can thin out tooth enamel, so too can acids in the diet, said Dr. Katz. That's why some of the worst foods for your teeth include citrus fruits and juices, tomatoes, pineapples, vinegar, carbonated beverages, some sports drinks, and certain salad dressings that are vinegar-based. A recent study in BMC Oral Health confirmed that acidic beverages have an erosive effect on teeth. That doesn't mean you need to cut all of these out of your life entirely, especially the ones that are good for you. But it is a good idea to sip some water after eating or drinking them, advised Dr. Katz, adding that consuming more water can prevent staining as well, especially from things like blueberries, dark tea, and red wine. You run on coffee. Although researchers have suggested that the caffeine and antioxidants in coffee can yield some health benefits, like increasing your longevity, it's a beverage that can be tough on your teeth, said dentist Katia Friedman, D.D.S., co-founder of Friedman Dental Group in Florida. 'Sipping two or three coffees every day allows the enamel of your teeth to be in constant contact with a staining agent,' she said. Since enamel is porous, these stains can settle in and cause yellowing if they're not regularly rinsed and brushed away. It's not the quantity of coffee that's a concern, it's the sipping that can be especially damaging, Dr. Friedman said. Drinking coffee more quickly, or even through a straw (as long as you're positioning the straw behind your teeth), can reduce the amount of time the staining agents linger in the mouth. And research in the Italian Journal of Food Science warns that you should be aware of black tea as well, as it can have the same staining effect. You smoke cigarettes. The chemicals in cigarettes and pipe tobacco have a staining effect on teeth because they cling to enamel, said Dr. Friedman, and the longer you smoke, the more visible this becomes. Smoking has also been associated with a bevy of other oral health issues like gum disease, tooth decay, and bleeding gums, per the Centers for Disease Control and Prevention—so consider whiter and stronger teeth just one more reason to consider quitting. You aren't following your dentist's orders. Past surveys by the CDC and American Dental Association have found that only 30 to 40% of adults floss their teeth daily. And yet, this simple practice could be the key to preventing your teeth from yellowing. Dr. Friedman said that being less-than-consistent on brushing and flossing can cause an accumulation of plaque on your enamel. This can thin that protective layer, and also cause your teeth to appear yellow from the film of bacteria. A good home-care regimen, coupled with an in-office cleaning at least once a year, can go a long way toward scrubbing that yellow out, she said. You're brushing too hard. While it's great to have a regular brushing routine, more pressure and speed doesn't mean a healthier mouth—in fact, it could have the opposite effect, noted Mazen Natour, D.M.D., a Manhattan-based prosthodontist. This can be especially true if your toothpaste contains abrasive agents, such as choices that aren't approved by the American Dental Association, he adds. 'If you brush too hard or too often, you might wear away the thin enamel layer and expose the dentin layer,' explained Dr. Natour. If your teeth are already yellowing, check with your dentist for professional whitening options as well as advice about changing your habits, he suggested.

Does Toothpaste Without Fluoride Stop Cavities?
Hi, it's Micah in New York. I used to hate going to the dentist. Now I'm focused on protecting my teeth, which made me wonder about these non-fluoride toothpastes I've been hearing about. More on that in a moment, but first ... Fluoride-free toothpaste sales have jumped ever since US Health and Human Services Secretary Robert F. Kennedy Jr. questioned the safety of fluoride.

Missing A Tooth? Scientists Develop New Drug that Regrows Teeth
If you're one of the millions of people who have a gaping space in your gums where a tooth used to be, there's reason to hope you might not have to spend the rest of your days with an uneven smile or fake teeth. Scientists in Japan have announced that they are moving forward with a drug that is capable of regrowing human teeth, Popular Mechanics reports. The drug works by suppressing an antibody called uterine sensitization–associated gene-1 (USAG-1). In ferrets and mice, this protein is shown to inhibit the growth of teeth, according to Dentistry Today. In a press release, Dr. Katsu Takahashi, a lead author of a study from Kyoto University and the University of Fukui, said, "We knew that suppressing USAG-1 benefits tooth growth. What we did not know was whether it would be enough.' He adds, "Ferrets are diphyodont animals with similar dental patterns to humans.' An article from Dentistry Today reports that researchers found that the 'USAG-1 protein could limit the growth of teeth in mice.' And that suppressing the protein would 'potentially invite their teeth to grow.' Trials conducted on mice were successful. Even more exciting, Dentistry Today reports, is that Takahashi's previous research shows that humans have a third row of teeth in their mouths. Those teeth are available as buds, and Takahashi believes they can be activated. The human trial for regrowing teeth is expected to last about 11 months, according to Popular Mechanics. Originally, it will consist of 30 men between the ages of 30 and 64. A qualification is that they each must be missing a tooth, an article in New Atlas reports. The article also states that if the trial is proven safe and effective, plans are to open the trial to patients between the ages of 2 to 7, who are missing at least four teeth. Researchers hope to have the drug available by the year 2030, Popular Mechanics A Tooth?

The Creator of SQUID GAME Lost 10 Teeth While Shooting The Series; and He Hasn't "Put Them Back in Yet" — GeekTyrant
Squid Game series creator Hwang Dong-hyuk recently revealed that the production of the series has taken a physical toll on him as he lost a lot of freakin' teeth! While speaking with Entertainment Weekly, Hwang talked about shooting Season 3 and confessed: 'I thought it was going to be okay, but this time I had to pull out two more teeth as well. I had to pull out about eight teeth in season 1, and now I have two teeth more out, and I haven't put them back in yet. So I'm waiting for them.' That's a total of ten teeth sacrificed at the altar of deadly children's games, existential dread, and masked game masters. What the hell!? Was he so streessed out that his teeth were just falling out of his head! This is a nightmare that I have, for real! While most people lose sleep over work stress, Hwang seems to lose molars. I guess this shows just how much pressure he's under to deliver a finale worthy of the cultural juggernaut he created. Season 3 will bring the mainline series to a close, but Hwang's not ruling out the possibility of a spin-off. He explained: 'If I make [a] spin-off, it will be a story happening between season 1 and 2. There [was] a three years gap between season 1 and 2. So, I want to show what they did for those times.' As for what lies ahead, Netflix's official synopsis reads: 'Gi-hun, a.k.a. Player 456, [is] at his lowest point yet. But the Squid Game stops for no one, so Gi-hun will be forced to make some important choices in the face of overwhelming despair as he and the surviving players are thrust into deadlier games that test everyone's resolve.' And if that's not enough to rattle you, series star Lee Jung-jae warned fans at Netflix Tudum 2025 that the new season will 'shock the world one last time.' Squid Game Season 3 hits Netflix on June 27. Here's hoping Hwang gets some well-earned rest… and a good dentist.
