Is there a way to clean hardened plaque from teeth other than going to then dentist? I'm beyond the point where baking soda works.
Go to walmart, by a dental hygiene kit. use the tools in the kit to remove your plaque. I have done this for years. i also polish my shoes rather than buy new ones. I cut my own hair. I sharpen my electric shaver blades. i brew my own wine. i fix my own flat tires (kits at walmart), i built my own house. I am one cheap bastard. i will even eat paleo food rather than pay doctor bills.
Why not go to a dentist? If money, many dentists offer 1st time cleaning rates of around $50, and many university-affiliated dental schools feature low-cost services. Also look for free clinics in your area, and check Craigslist for students seeking patients for licensure exams...
I still go to the hygienist occasionally to get my teeth cleaned. Not cheap but I've never managed to get anything close to the amount of plaque my hygienist removes. I would really recommend talking to your dentist if it is a big concern. Better diet and dental habits make the need for visits less I find but it makes a big difference to get a helping hand every so often.
Once it becomes plaque you are fairly powerless to do anything yourself and really need a dental hygienist. Go to the dentist, get it taken care of, then keep your teeth clean from then on!
Perfectly clean teeth with vitamin K2. I've stopped going to the dentist for teeth cleaning altogether. Adding vitamin K2 -- the MK-4 from Thorne Labs -- cleaned the calcified krud off the back of my lower front teeth in 2 days! Truly amazing! Now my teeth are smooth and clean all the time. I just brush my teeth once a day (I don't drink coffee or tea, no stains.) I'm saving good money without the dentist 2x year. I learned about it from Richard Nikolay at Free the Animal. (Read down near the bottom) The vitamin K2 is a hard to get vitamin, even if you eat the best pastured eggs, butter and organ meats. It's the 'X-Factor' that Dr. Weston A. Price discovered. It puts the minerals where they are supposed to go, instead of calcifying your arteries and joints. Be sure to get the MK-4 version of vitamin K2. And even though the Thorne bottle costs alot up front, you only need several drops a day -- so the bottle will last you all year. Bottomline: if we get all the nutrients we really need, our body should be clean and smell good -- like all primitive people were.
For plaque, I think you should be able to remove it daily by brushing either with regular (i.e., fluoride containing) or organic toothpaste. More important is to floss, which is de rigueur anyway if you eat beef or berries. Based on my survey, only a tiny minority of the population (~5%) knows how to floss and does so daily. I did not learn how to floss properly until I became a committed beefeater a few years ago.
My main dental concern is not with the plaque but with tea and coffee stains that are hard to remove. According to my dentist, there's no reliable way of removing tea stains from your teeth other than to continue to see him every 6 months(!) I drink about 5 cups of green and black tea everyday and the cost of all that polyphenols is my permanently brown teeth. It's even worse in the back of my teeth.
I am one that does not like to have any chemicals on me or in me. I am also one that is not up for paying to have the dentist sit and argue with me over my choices in health. They always want to give me fluoride - which is in fact rat poison and a neurotoxin as @raydawg said above. The dentist, just like your doctor believes conventional wisdom. I know I sound crazy, sorry.
I stopped using toothpaste awhile back. I just use a bar of non glycerin soap and brush away. My teeth have never felt so clean. I am seeing a huge amount of my plaque just come off, I only have 3 teeth that I can still see it on and the area is getting smaller! I came across this book “Good teeth, birth to death” by Dr. Judd. Dr. Judd explains that when we brush our teeth with conventional tooth paste that the glycerin in the toothpaste (all have it, even organic ones) coats are teeth. This is what the glycerin is there to do, protect the teeth from stains. However, if you have this coat of ‘gunk’ (if you will), on your teeth then your enamel will not regrow. So then your teeth are just getting beat up, then covered with a thin barrier wall. Sure this barrier wall is great, but it is not natural and has adverse side effects. If you have a layer of glycerin on your teeth they can not repair themselves, thus you get sensitive teeth or cavities or rot. And the fluoride in your toothpaste it not helping.
Long story short the book is great if you are really interested in your teeth's health. It is a free book too. If you are interested in what I am doing /have done I wrote on my page about it and am tracking my progress with photos of my teeth. I really have been shocked by the amount of money I am saving (my bar of toothsoap barley has a dent into it 1/2 a year in), I have no sensativity anymore and my teeth are getting whiter.
This might not be a fast way to get rid of the plaque you have.. but it might be the most natural and gentle. Let me know if you have questions about it.. :)
