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 ...
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, ...
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 ...
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. Mayo Clinic:
If you've eaten an acidic food or drink, avoid brushing your teeth for
at least 30 minutes. These acids weaken tooth enamel, and brushing too
soon can remove enamel. If you know you're going ...
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....
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 ...
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.

What makes toothpaste sweet?
Why is toothpaste sweet and what is it sweetened with?
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 ...
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 ...
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.
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: ...
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
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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.
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.
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 ...
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

The age-old adage "the dose makes the poison" applies here. With ingested medications, dosage is more simple to conceptualize: how much did you swallow. With topical creams: how much did you apply. But with swish-and-spit oral solutions where a copious amount is applied topically then disposed of, it's the DURATION of application that determines dosage ...
Some recent estimated numbers recently were:
45% of all dental restorations world wide (Heintze 2012),
50% of all American fillings
Many developed nations have virtually eliminated dental amalgam. Dental amalgam use is banned in Sweden and Norway; only used in 3% of all dental restorations in Japan and Finland; 5% in Denmark; 10% in the Netherlands,...
This interaction relates to a broad family of hormones called catecholamines. There are many examples and they share a common structure.
Notice the common structure of catechol (the carbon ring with two hydroxyl (OH) groups) and an amine (NH2) group.
This group of hormones and neurotransmitters act as ...
Oil pulling is an ancient Ayurvedic practice that essentially involves
swishing around oil in the mouth. Similar to a mouthwash, the oil
“pulls” bacteria and toxins out of the mouth and, over time, can leave
your teeth whiter and your gums healthier. And while oil pulling may
seem a little “woo woo” at first, many studies have proven ...
