Consult Dr. Huaxi. Are you experiencing any of the following 10 dental health issues?

▽

1. Dr. Huaxi, I want to ask about my wisdom teeth. I get an inflammation every two months, which lasts for more than a week. It is very painful! Do I have to extract them? I saw some people say that wisdom teeth do not need to be extracted. What is the situation?

Answer: In a case like yours where wisdom teeth frequently become inflamed, it is recommended to have them removed early, but you need to wait until the inflammation subsides and the redness and swelling disappear before doing so, otherwise changes in the oral environment will affect the effectiveness of the anesthetic.

Most wisdom teeth are of the "bully type". Not only do they grow crookedly, but they also collide with normal teeth in a despicable way. More importantly, they are prone to breed bacteria, cause tooth decay, cause inflamed and swollen gums, jaw cysts, oral ulcers and even cancer.

But there are also those wisdom teeth that are "pure and innocent".

This excellent wisdom tooth should of course be kept to serve us, as it grows neatly, has perfect upper and lower bites, can be cleaned, and does not get inflamed from time to time .

2. This question is asked for my child, who is 10 years old this year. Because his teeth are a little bucktoothed, other classmates at school always call him "Wang Bucktooth"... As a parent, I still feel uncomfortable hearing this. I heard that it can be corrected by braces?

A: I understand the parents' feelings. Professionally, we call dental deformities such as buck teeth and underbite "malocclusion", which are divided into two types: dental deformity and skeletal deformity .

It is recommended to send the child to the hospital for examination to determine whether the cause of buck teeth is “dental” or “bone”.

If it is "tooth-related", then it is relatively simple. Through braces , you can get a set of neat white teeth in a few years.

If it is "bone", it will be a little tricky. Mild symptoms can be treated with braces, but severe bony deformities require orthognathic surgery.

If braces are suitable for correction, you can listen to the doctor's advice on the timing and choice of braces. It is not necessarily the case that the earlier the time or the more expensive the braces, the better.

3. It's my turn now, Dr. Huaxi. I usually like to be clean and I always floss after meals. Someone told me that if I floss too much, the gaps between my teeth will get bigger. I looked at it and it seems to be true. Is it true?

A: Who told you that flossing will make the gaps between your teeth bigger? Ask him to join us in the comment section to have a battle?

Flossing is a very good habit that can effectively remove residues in the "hygienic dead corners" between teeth and maintain oral hygiene and periodontal health.

The reason why you feel that the gaps between your teeth become larger after flossing is usually because you don’t floss often, and flossing increases the “feeling” of the existence of the gaps between your teeth. To put it bluntly, it’s a psychological effect.

No problem, continue to use it with confidence!

4. My teeth are too yellow! My teeth are too yellow. Why are they still so yellow even though I brush them carefully every day? Why?

A: Well, because the purpose of brushing our teeth every day is not to whiten them...

The purpose of brushing teeth is to remove dental plaque, food debris, and pigments that are not so tightly attached to the surface of teeth. It has the effects of freshening breath, beautifying the appearance, preventing caries and tooth decay, and preventing periodontal disease.

The hard tissue of our teeth is divided into two layers:

The first layer is the softer dentin inside, which is yellow in color;

The first layer is the hard enamel on the outside, which is white with a certain degree of translucency .

So if your teeth are **“white with yellowish”**, congratulations, your teeth are very healthy!

5. I received the previous question. With the increasing awareness of health, I have to have my teeth cleaned every year. Does teeth cleaning have a whitening effect? ​​Also, will it damage the teeth?

Answer: You may say that teeth cleaning does have a "whitening" effect. The principle is that teeth cleaning removes dental plaque and pigments on the surface of teeth to a certain extent, giving a "whitening" effect.

However, what appears after teeth cleaning is the "yellowish white" of healthy teeth as mentioned above. It is not realistic to expect to achieve a "bright white" effect.

Many people are also worried that teeth cleaning will cause teeth to loosen, damage tooth enamel, etc., but this worry is actually a bit unnecessary.

Nowadays, ultrasonic cleaning and sandblasting are commonly used for teeth cleaning.

👉 Ultrasonic teeth cleaning uses smooth and non-invasive high-frequency vibrations to vibrate and loosen dental plaque instead of grinding it away.

👉 Sandblasting teeth cleaning uses the principle of high-pressure water, air and sand to remove dirt from the surface of teeth.

Therefore, as long as the operation is correct and the technique is appropriate, no damage will be caused to the teeth.

6. It’s still about brushing teeth… I brush my teeth diligently every day, but why do dental plaques still grow? I can’t brush them off!

Answer: In fact, newly formed dental plaque is relatively soft in texture and can be removed through correct brushing, rinsing, and flossing.

But many times, we do not use the correct scientific method to clean teeth , such as ignoring the dirt in the gaps between teeth, which will cause dental plaque and mineral salts in saliva to easily "settle down" in the gaps between teeth and on the roots of teeth.

Over time, calcified dental plaque becomes hard and either turns yellow or black. It cannot be removed by brushing your teeth. If not cleaned in time, it can induce gingivitis, periodontitis, etc. It can only be removed by teeth washing.

Therefore, daily proper cleaning is very, very important!

7. Dr. Huaxi, my teeth are very delicate. I can’t let cold water touch them, eat fruits, or drink carbonated drinks. They are more difficult to take care of than my son!

Answer: There are indeed too many scenes. This situation is mostly caused by tooth sensitivity.

Tooth sensitivity is the symptom of soreness and pain caused by external stimulation of the teeth. It occurs quickly, the pain is sharp, and the duration is short. It is a common symptom of various dental diseases.

It is generally believed that there are two main prerequisites for tooth sensitivity:

One is that the protective layer on the surface of the tooth (such as enamel and cementum) is destroyed (gingival recession, etc.), exposing the deep dentin ;

One is the stimulation from inside and outside the mouth , which causes tooth sensitivity because the teeth cannot adapt to it for a while.

If tooth sensitivity is not treated in time, it may also lead to serious consequences such as pulpitis and apical periodontitis.

In addition, tooth sensitivity can also affect the patient's implementation of oral hygiene measures, causing diseases such as gingivitis and periodontitis, and reducing the patient's quality of life. Therefore, it is necessary to choose the appropriate treatment plan as soon as possible after a doctor's differential diagnosis.

It should be noted that tooth sensitivity cannot be completely cured at present, and the only way to relieve the sensitivity symptoms is through treatment.

8. I have a very "simple" question to ask Dr. Hua Xi: I know that eating too much sugar will cause tooth decay, but someone told me that eating fruit is not likely to cause tooth decay, but squeezing it into juice is likely to cause tooth decay. Why is that?

Answer: This is a very interesting question. Let’s first analyze the thing called sugar: Sugar is divided into non-free sugar and free sugar.

👉 Non-free sugars are less harmful to the body

👉 Free sugars are more harmful

Non-free sugars refer to fructose that naturally exists in fresh fruits, sugar in vegetables, lactose in milk, and starch in cereals and potatoes.

There are two types of free sugars: one is the sugar found in fruit juice and honey, and the other is sucrose, glucose, fructose and syrup added to food during food production and processing.

So the conclusion is that the non-free sugars in whole, fresh fruits are wrapped by a layer of plant cell walls, which are slowly digested and are not likely to cause tooth decay .

But when fruit is turned into juice, it becomes free sugar , which may sound "healthy", but the possibility of causing tooth decay increases .

Therefore, the same fruit, eaten in two different ways, has completely different effects on oral health.

9. Emmm, I am the unlucky guy who got cavities from eating too much sweets, but there is one thing I don’t understand. When I went for a check-up that day, I was found to have cavities, but can’t cavities be cured by filling them? Why did the doctor still ask me to do "root canal treatment"? I get scared when I hear about root canals!

Answer: If it is just simple tooth decay and there is no obvious pain, you can just remove the damaged tooth tissue and fill it as you said.

However, when a tooth suddenly starts to hurt without any stimulation and the pain is worse at night than during the day, this is an inflammation of the dental nerve .

For adults, the only way to completely solve the inflammation of the dental nerve is root canal treatment .

Root canal treatment involves three steps: pulp opening, root canal preparation, and root canal filling. It usually takes 2 to 3 times (it is possible that some unlucky people may have to do more).

In addition, you don’t need to be afraid of root canal treatment. Nowadays, anesthetics are usually given in advance, so it can be "painless". Of course, if you are stubborn and want to experience the pain, you can also ask the doctor not to give you anesthesia...

10. The last question is, can periodontitis be cured? I have seen many drug advertisements saying that anti-inflammatory treatment can completely cure it.

A: Oh, this question really touches us! Many patients with periodontitis ask, "Doctor, what anti-inflammatory medicine is better for periodontitis?"

I don't know when "inflammation must be eliminated" became a deeply rooted idea among everyone, which gave opportunities to all kinds of miracle drugs, claiming that periodontitis can be cured by reducing inflammation.

This is completely nonsense! Huaxi doctors can tell you with certainty that there is no magic drug on the market that can cure periodontitis.

Periodontitis is not caused by inflammation, and the treatment method is not to reduce inflammation and eliminate inflammation, but to control dental plaque . And if it is not treated correctly, "a mouth full of teeth" will be a high probability event.

If you have the financial resources to "drive a Mercedes in your mouth", then you can just leave it alone and grow a new set of teeth. If you don't have that kind of financial resources, then you'd better get treatment.

"Although teeth are the only part of your mouth

Hard parts of the body

But if you don't treat it well

Not brushing teeth, not cleaning teeth, smoking

…

Consume it recklessly

You wait until

One day these debts

You still have to pay it back yourself
