I believe that those lines are craze lines. "Craze lines are merely cracks in the enamel that do not extend into the dentin." They occur because of stress in your teeth, ie: grinding your teeth, biting your nails, and even routine use of your teeth. What you've said also matches up with craze lines in that you don't experience any pain. Those craze lines ...

Most dentists - for most procedures - aim for a painless experience. If there is reason to keep some pain sensation intact, the dentist will inform you, and ask at appropriate intervals if you can feel pain. The efficacy of lidocaine and other local anesthetics depends on how closely your nerve distribution comes to the norm (they will inject the environs ...

Short You should brush, 20-30 minutes after eating on the night (just before you sleep) and, 10-20 minutes before eating your breakfast. Midday brushing, is not essential for most albeit, it's highly dependent on your dietary habits. The same rule applies: 20-30 minutes after eating or 10-20 minutes before eating. The time-rule is influenced/is-in-place to ...

There are certain types of malocclusion that are have been shown to adversely affect quality of oral health and quality of life, but these are far, far fewer than the number of people sporting braces, adult or adolescent. The need for braces in the average teen, therefore, is no greater than the average adult. If you think of braces for teens as a necessity, ...

Yes. The acid in the food can harm the enamel and brushing it to soon can remove it. So wait at least 30 minutes, brush before or avoid acidy foods.

Fluoride can be absorbed into the teeth and form fluoroapatite only in children up to 6-8 years of age (WebMD). Later, fluoride from toothpaste may still be helpful, because it stimulates the incorporation of calcium and phosphorus into the enamel that has been demineralized (PubMed Central, 2006). So, fluoride stimulates remineralization and thus slows ...

Dental flossing, essentially is done to maintain periodontal health, in hard to reach areas. Areas which are not used to any "friction" so, they will react in a rather singular manner in comparison to our exposed gums, per say. Thus, providing you presently have good oral health i.e. you don't have gingivitis which causes bleeding of the gums amidst brushing....

It can absolutely give the dentist information which will help him identity potential problems. I recently had a root canal. It was a two-visit procedure, and on the first day, he drilled out the nerve fibers, tissue, and pulp, then placed a temporary crown over the tooth. The second visit was supposed to be a simple matter of removing the temporary ...

I can speak from personal experience, and from experience working as a physical chemist peripherally associated with a group researching dental care. My personal experience is that I have a few lesions that my various dentists over the last couple of decades have decided not to fill because they are not serious and not getting any worse. So a dentist will ...

The anesthetics used for the root canal are not very long lasting. An example of the longer-acting local anesthetics is Bupivacaine. The average half-life of Bupivacaine Hydrochloride in adults is 2.7 hours (that is, within 2.7 hours, half of the total dose absorbed is metabolized. In people with liver or renal failure, it may be longer, as it is ...

I found a study which show that teeth whitening using Hydrogen Peroxide can cause oral mucosa irritation, burns or sensitive teeth. However, these were found to be mild in nature and resolved spontaneously without any intervention. Since teeth whitening strips are hydrogen peroxide based, I think the results can be safely extrapolated. References: Teeth ...

Artificial sweeteners are used in toothpastes. Mostly Xylitol or Sacharin. They don´t promote tooth decay. The sweetness in toothpaste are added in order to make more people brush their teeth on a daily basis. Livestrong - Saccharin Safety in Toothpaste What makes toothpaste sweet?

The bacteria that produce these foul smelling odors are anaerobic bacteria that live in the oxygen depleted film left on our teeth, tongue, and roof of our mouth if we don't brush. These bacteria can produce chemicals that cause malodor including: volatile sulphur compounds (VSCs), mainly methyl mercaptan, hydrogen sulphide, and dimethyl sulphide diamines ...

Green tea, or any real tea made from the Camellia sinensis plant, has many advantages as a go-to beverage. It itself does not contain significant amounts of sugar, it has an enamel preserving pH level (that is: it is non-acidic). Some compounds (like the poyphenols) have shown some activity against harmful bacteria causing gingivitis or caries. The most ...

The latest systematic review in this issue found: there is only weak, very low quality and unreliable evidence avalaible for floss the magnitude of the effect was small, for woodsticks and oral irrigators was weak and for interdental brushes was large Main conclusions are: There is weak evidence that flossing plus toothbrushing compared to toothbrushing ...

Your question seems to be about the "cleaning" or periodontal maintenance portion of your appointment. (Periodontistry is a field in dentistry which is concerned with the gums or soft tissues around teeth) As part of an initial exam or routine checkup, many dentists and their hygienists will perform all or some of the following steps: Assess if there were ...

The NHS says (emphasis mine) Brush your teeth for about 2 minutes last thing at night before you go to bed and on 1 other occasion every day. They don't specifically stipulate as soon as you get up or after breakfast, but brushing in the morning is important because during the night, the formation of plaque is mostly undisturbed. Brushing after each ...

I will answer your questions separately: 1) Teeth can shift on their own, due to the fact that they are supported by the periodontal ligament (PDL) that holds the teeth by their roots in your mouth, while still allowing them to move slightly. Think of it as a shock absorber. Most movement of teeth happens due to pressure that is applied to your teeth (ex: ...

Couldn't find any articles directly looking at effervescent tablets and dental problems, so I took a more broad look and searched for citric acid's effect on teeth. The combination of citric acid and sodium bicarbonate are routinely used in effervescent tablets designed for human consumption (according to Wikipedia ;). Citric acid is commonly found in many ...

Comparing "saltwater" to non-alcoholic mouthwash may be too general. If I remember correctly, pH is dependent on OH- (hydroxide) and H+ (Hydrogen) levels. Depending on the type of salt, let's say NaCl (table salt), water will recombine with the salt, but OH and H levels aren't affected. Na binds to OH and H binds to CL in equal quantity. Regarding the ...

Good evening, The reason the abscesses in your mouth won't heal on their own is due to: The fact that the mouth is one of the areas of the body with the most bacteria Therefore, the immune system cannot get ride of all bacteria, especially when they reside in or around teeth, which are relatively poorly vascularised and doesn't regenerate after being ...

Analysing the papers already cited in the question and further looking for evidence there seems to be some promising research going on. Honey has bactericidal properties, Manuka honey even more so. Sounds quite logical then to use this honey in helping with oral troubles as a result of bacterial activity? Honey contains so much sugar(s) that it's tempting ...

Yes, the presence of calculus prevent the demineralization of the surface of the tooth. This is a common finding during routine scaling or calculus removal, where usually the underlying enamel is intact. Also, there is a paper about this issue: Evidence for putting the calculus: caries inverse relationship to work who found caries prevalence is highly ...

Basically you're asking how to overcome a compulsion you feel about your mouth hygiene. That is no small feat, especially since you're already aware of the problems associated with over-brushing. In general, obsessive thoughts/compulsive behaviors are differentiated from simple worries by, among other things, being more frequent, distressing, associated ...

First, some quote from British Fluoridation Society webpage (which text is based on some article authored by dr Levine, author of "The action of fluoride in caries prevention. A review of current concepts"): The relationship between fluoride and tooth decay is complex and probably not yet fully understood. However, it is known that fluoride interferes ...

More dangerous than healthy teeth, but not impossible to live with. A cracked tooth has a higher risk of breaking, is less resistant to tooth decay, heat, cold, acid etc. The 2 most dangerous situations I can imagine: If the weakened tooth breaks apart, its parts can be as dangerous as shards of glass in the mouth. If the injury leads to osteomyelitis, it ...

Some vendors publish the pH values for the products they sell (examples in this answer). But that seems to be only the case if their product really stands out to the competition with high pH levels. Simple carbonated water (de-ionised) can have quite a low pH but other factors come into play for the acidity of the finished item. This brand's website has a ...

Well, you could die today and that would make the answer yes. https://www.scientificamerican.com/article/why-do-some-people-get-mo/ Dental caries is the most prevalent infectious disease in humans, affecting 97 percent of the population in their lifetime. From the above we can conclude that 3% of the population go their entire lives without a cavity.

The main protective effect of fluoride is outside the tooth, not inside. Small amounts of fluoride in solution around the tooth inhibit demineralization more effectively than incorporated fluoride and have a much greater caries-protective potential than a large proportion of fluorapatite in enamel mineral.
