Floss and electric toothbrush, brush twice a day, works wonders. One of those brushes that make sure you brush each quarter for 30 seconds for a total of 2 minutes.

I maintain very good dental hygiene, and my dental hygienist always loves me. These are the tips I've picked up from them as I've gone

• Use an electric toothbrush. My hygienist didn't give a recommendation, but I asked what she used and said the Philips Sonicare and really liked it. I got one for $25 on a black friday sale (normally $50 for the model I got). I'm sure plenty would work, but one that also tells you when you're pressing too hard is a very nice perk, and the timer is a must.
• Floss every day with normal string floss. Honestly, quickly disrupting the bacteria between your teeth is good most days, and then give it a really good go other days to really break things up.
• Never brush with a low pH level in your mouth. Eating anything increases the acidity in your mouth, so wait about 30 minutes before brushing. Some things increase it much more, such as soda. Wait an hour or so after drinking soda or other acidic foods/drinks before brushing. Drinking water can help normalize the pH levels faster, as well. So if you must, just swish around some water a good bit before brushing.
• Saliva is good for you. If you drink a lot of soda or eat a lot of sugary foods, stop it. But since you probably won't stop (like me) chew sugar free gum to increase saliva production to help fight the sugary-ness of it, as well as help balance the pH levels a little.
• Use alcohol free anti-cavity mouth wash. It's basically just water and fluoride, so if fluoride toothpaste doesn't hurt your mouth, you should be okay with this mouthwash.
• Make sure you're using fluoride toothpaste. It doesn't need to be fancy, I just use the cheapest fluoride toothpaste.
• Do not rinse out the toothpaste in your mouth after brushing. You want the fluoride to stay on your teeth for as long as possible. And if you do end up using flouride mouthwash, do not drink anything for at least half an hour after using it to make sure the flouride has time to work. The longer it's on your teeth, the better.
• Brush AT LEAST every night. Of course they always recommend twice a day, but if you picked one, do it before bed and not in the morning. If you don't brush before bed, the bacteria from the day will sit on your teeth all night going to work on you. I only brush at night, but the hygienists I have always say they wouldn't have known if I hadn't told them. And that's even with habitual soda drinking habits.
• Accept the fact you will get tartar build up. It's going to happen, despite your best efforts. That's why you should go to the dentist every 6 months. They will remove the tartar build up with a metal pick, but if you do everything above, it should be an easy job for them.

Consider chewing Xylitol gum after eating. Xylitol directly fucks up the bacteria that cause tooth decay. Make sure to get a brand that is mostly Xylitol (I like Pur).

However, be careful if you have a dog, because xylitol is super poisonous to dogs!

Have you tried changing your brushing technique? From my time working in a dentist's office as an assistant, its usually the brushing technique that most people get wrong. You're supposed to focus on where the teeth and gums meet.

I recommend the first 2 from the link above. They're the most similar to how most people already brush their teeth so its an easy transition. The only real difference is you angle your toothbrush 45° away from the surface of your teeth. Doesn't matter if you angle it up or down.

I also had this issue. I was doing everything I could think of to take care of my teeth, but I’d go to the dentist and they would comment about plaque and signs of receding gums. I switched to an electric toothbrush and waterpik. I was actually able to reverse some of the recession (verified by having the dentist take measurements, not notable by just looking)

Electric brushes usually help with that. Do go for a brand like Braun or Philips though, otherwise it's easy to end up with a toothbrush with non-existent or low-quality replacement heads. You don't need an expensive model from those brands. Those work about as well as the cheaper models and only include more frills, and their replacement heads are often more expensive too. The only feature I actually find helpful is the 30-second/2-minute timer which most models have nowadays.

Waterpicks for me have been amazing! I got one for like 30 USD and I use it once or twice a week. It makes my teeth feel so much cleaner and I feel like they stay cleaner too. It also gets stuff stuck between your teeth instantly without having to do weird flossing gymnastics. I’ve always sucked at flossing but with the waterpick I actually use it regularly.

Electric toothbrush, don’t want to shill for a brand but Oral-B.

I'm sorry, mouthwash peels your skin off?!

Sonicare toothbrush, then floss, then waterpik. The kids waterpik is cheaper and does the same thing.

Electric brushes (with regularly changed tips) can be amazing. There are also some inexpensive ultrasonic ones and I’m absolutely happy with mine. It’s a whole other level than handbrushes.

The plaque forms as a result of bacteria eating the sugars that stay on your teeth. Most dentists in my life have recommended brushing right after eating.

You need to figure out why mouthwash peels your skin off.

That is not normal and is almost certainly related somehow to the plaque buildup.

there is likely no way to entirely prevent it, but I have been using a sonicare for about nearly 20 years and have had 0 problems with my teeth. I cannot recommend them enough—everyone should have one.

Arm and hammer toothpaste with baking soda is great. Clinical studies have proven a statistically greater reduction in plaque than toothpaste that does not contain baking soda.

Use a toothpaste or mouthwash containing https://en.wikipedia.org/wiki/Chlorhexidine

I asked my dentist this, and she just said that I have fast plaque buildup and there's not much I can do about it other than getting my teeth cleaned once a year

Could probably drink less coffee though

Get a good toothpaste, brush twice a day, change my toothbrush once a month (whether it's electronic never changed my success rate), and go to the dentist twice a year. My dentist says I have model teeth.

While I think brushing, flossing, mouthwash all play an important role. Nobody is teaching you how to breakdown the actual problem. Besides genetics if your hygiene is sufficient. The food and drinks you consume are to blame. Bacteria are influenced from your diet. Change what you consume and your bodily systems will adjust accordingly, that being said cause and effect should be noted. Changing one system will modify others good or bad. Tailor your intakes based on the symptoms your trying to mitigate by learning how those systems work individually and then cohesively together. The fastest way albeit quite inconvenient is to log every food, drink, and consumable item that goes into your mouth each day for X number of days and find trigger foods which cause your symptoms. Analyze and extrapolate the data. Refine through trial and error. Tailor your diet to suit.

For me I use Phillips soniccare tooth brush which is infinitely better than a manual one. Have you tried your luck with iodine mouthwash? It's more expensive and tastes gross but it's really good for gingivitis and doesn't burn. Also if you aren't already, flossing everyday and maybe after each meal if needed is important. Floss has to be reaching below the gums to pull out the trapped food and not just in between the teeth.

Have you asked your dentist?

You seem to be doing quite some things well. Maybe pay attention to your brushing? My dentist once had me brush my teeth in front of her and identified why in some teeth I'd consistently be clean and in others I'd consistently build plaque.

Her recommendations: brush from the gum to the tip of the tooth. Try to aim at the holes between teeth. Pay close attention to the part in front of your tongue, in your lower front teeth; that part can easily build plaque if you don't use the tip of your brush well to get in the holes between your teeth.

I spent several years intermittent fasting, only eating between 6pm and 10pm. I didn't do it for my teeth but it did help keep them much cleaner, probably obvious in retrospect. It's not a healthy diet in a lot of other ways though.

My trusty 16 year old sonicare toothbrush, a tongue scraper, and a water pik make it so I barely get fuzzy teeth unless I eat a bunch of sweets or crackers. I also swish with OralB gum detoxify mouthwash every once in a while, but I didn't have much plaque even without using it.

The other oralb washes aren't as great imo, but the gum detoxify has zinc and cetylpyridinium chloride in it which both inhibit bacteria. No alcohol in it either which is what causes most mouthwashes to burn. It does cause you to spit out a white film immediately after which I assume is dead bacteria. Never had any irritation with it and a doctor actually recommended it to me when I had strep throat which it helped.

Also Walmart carries a sonicare 1100 that is only around $20. I use that when I travel instead, and it's just as good as my older more expensive electric toothbrush.
