What are the common causes of yellowing and blackening of teeth? What are the methods to prevent tooth blackening?
There are basically two categories: external stain and internal stain.
The outer layer "stained" is caused by drinking coffee, tea, red wine, smoking, and even eating fried kway teow, chocolate, curry, etc., which turns the teeth yellow and causes stains. But for dentists, it is not too difficult to remove this layer of color.
The inner layer "staining" can make the growing teeth "discolored" by taking some antibiotics from time to time. When the teeth are molded, they usually fade.
First, dental fluorosis can occur if a person lives in an area where the fluorine content in the water supply is too high from birth to 7 years old. Dental fluorosis is mild or severe, with chalky plaque on the tooth surface; In severe cases, the tooth surface forms a pit defect. Fluorosis due to pigmentation is yellowish brown or dark brown plaque.
Treatment: 1, yellow-brown or dark-brown dental fluorosis without defect can be bleached by laser in the hospital; 2. Dental fluorosis with substantial defects can be repaired with acid-etched composite resin to restore the shape of teeth and make the color white and luminous. Avoid drinking high fluorine water.
2. Tetracycline teeth can be damaged by taking tetracycline drugs, such as tetracycline, chlortetracycline and oxytetracycline, during the period of tooth development and mineralization, that is, before the age of 7-8. These drugs combine with hard tissues of teeth to form tetracycline calcium orthophosphate complex, which makes teeth discolored, called tetracycline teeth. Severe symptoms can also cause tooth hard tissue defects.
Treatment and prevention: The prevention method is that children under 7-8 years old are forbidden to take tetracycline drugs.
Third, people who smoke for a long time often have black pigmentation on their teeth. This is smoke particles, which are tightly adhered to the surface of teeth and cannot be brushed off by brushing, but must be removed by professionals in the hospital. After cleaning, you must smoke less and brush your teeth effectively every day to prevent pigmentation and keep your teeth clean and beautiful.
Fourth, natural yellowing: teeth are mainly composed of dentin, which is slightly yellow. With the increase of age, teeth will naturally age and accumulate more and more important dentin, causing teeth to turn yellow.
Treatment and prevention: laser tooth cleaning can be completely treated.
In recent years, with the increasing awareness of people's self-health, "tooth washing" has also been familiar to more and more people. Dental clinics that carry out tooth washing business have mushroomed, and even some beauty salons have written the word "tooth washing" on their signboards. There are more people washing their teeth, and some people have caused some troubles because of washing their teeth, which makes people have all kinds of discussions about washing their teeth.
Gingiva has a special tissue structure. The gingival margin is not closely attached to the tooth surface, but there is a shallow groove with a depth of 0.5-2 mm, which is called gingival sulcus. Normal elbow, gum and tooth surface close together, showing a closed state. Food debris and plaque are easily accumulated in gingival sulcus, which is a good area for anaerobic bacteria to grow and reproduce. Because it is closed and difficult to clean, it often leads to periodontitis. In addition, the area below the abutment of teeth is also difficult to clean thoroughly, and brushing alone can not completely remove foreign bodies, which may easily lead to periodontal diseases. Some people think that if you brush your teeth carefully every day, you don't have to wash your teeth, which is wrong. Because new dental plaque will form within half an hour after the teeth are thoroughly cleaned, it can reach the maximum amount within 30 days, and it will become dental calculus over time, which can cause gingivitis, periodontitis, bleeding, bad breath, and finally cause teeth to loosen or even fall off. Therefore, if adults have not washed their teeth, they should go to the hospital for a scaling as soon as possible, and it is best to do it once every six months.
What people commonly call "tooth washing" is called "scaling" in medical terms. The so-called "cleaning" means removing dental plaque such as bacteria, tartar and pigment from the tooth surface; And "treatment" means that it is one of the basic methods to treat periodontal disease. The inflammation of gingivitis and periodontitis can be alleviated by tooth washing, but periodontal disease cannot be cured by simple tooth washing. To cure periodontal disease, further diagnosis and oral professional treatment should be carried out after tooth washing. Therefore, the main purpose of tooth washing is to prevent and treat oral diseases, not just to look good.
In developed countries, tooth washing has become a very popular routine oral health care, and people regularly go to their dentists to wash their teeth once or twice a year. After tooth washing, if periodontal disease is found, the dentist will conduct professional oral treatment in time to maintain oral health.
Tooth washing is a highly professional technical work. In stomatological hospitals, it takes about three hours for medical staff to wash their teeth with manual instruments, and it takes about one hour to wash their teeth with an ultrasonic tooth cleaner. According to patients, it only takes 10 minutes to wash teeth in some dental clinics or beauty salons. Practice has proved that washing teeth in irregular places is very harmful. First, only the visible tartar is removed, leaving the deep tartar with the strongest pathogenic effect, which can not achieve the purpose of preventing and treating periodontal disease. Second, damage to the gums, especially when the roots are exposed after tartar removal, can not be further treated in time, which not only leads to unbearable pain for patients, but also aggravates the condition of periodontal disease. Third, it is easy to cause cross-infection and bring undue regret to people. Therefore, you should carefully choose the place to wash your teeth, and you should go to a regular hospital to find a strictly trained medical staff to wash your teeth.
So why do teeth feel strange or allergic after washing? After tooth washing, the gap between teeth is wide, will the teeth loosen? In fact, tartar is like a big cotton-padded jacket. Once you take off your teeth and expose them to a "long-lost" environment, you will have all kinds of strange feelings. If it is a healthy tooth, after a period of time, the strangeness will disappear. If the gap between the teeth is large, it means that there is periodontal disease in itself, and the gums have shrunk, which gives people the illusion that the gap between the teeth is widened after removing the calculus. This is not caused by treatment, but the cause of periodontal disease itself. If the tartar is not removed in time, the gums will shrink further, which will lead to loose teeth.
How to relieve toothache?
Toothache is not a disease. It hurts like hell. This statement has been circulated among the people for a long time. In fact, toothache is the external reaction of your teeth. It may be dental caries or the gums around your dental pulp or canine teeth are infected. Of course, cracks in your premolars can also cause toothache, and sometimes it is just vegetable scraps that get stuck between your teeth and cause discomfort. In addition, toothache may also be caused by sinusitis. If you have a toothache, you'd better find a dentist to find out the real cause of your toothache. But before going to the dentist, you can use the following methods to relieve the pain.
Rinse your mouth with a mouthful of water (the temperature is close to your body temperature), and rinse your mouth vigorously. If the toothache is caused by vegetable scraps falling between teeth, the toothache can be solved by gargling to remove the vegetable scraps. If gargling is ineffective, it can be removed by flossing. But be careful not to hurt your gums.
Anesthesia and analgesia contains a slightly strong wine, which can anesthetize teeth and gums and achieve analgesic effect.

Do not swallow.
Massage your hands. This method can relieve 50% pain. Take an ice cube and rub the V-shaped zone where the thumb and forefinger bones are connected. Gently press the ice cubes on this area for 5-7 minutes.
A Canadian researcher found that 60-90% people use this method, thus relieving toothache. His research shows that this rubbing method can interfere with the transmission of nerve impulses from toothache.
Ice compress is just like treating bruises. Ice compress on the cheek closest to the toothache can relieve the pain. Apply 15 minutes each time, at least 3-4 times a day.
Take antibiotics such as amoxicillin, and take one pill every 6-8 hours.

Why do you love toothache in winter?
The sudden drop in temperature makes some people's teeth ache obviously, and sometimes their teeth can ache for half a day by opening their mouths and taking a breath. The stomatologist of Union Hospital told everyone that this is mainly caused by dental caries or acute pulpitis.
According to the dentist of the Union Hospital, toothache is the most common symptom in oral diseases, which can be caused by many diseases, such as dental caries, acute pulpitis, periodontitis, acute and chronic periapical periodontitis, dentin hypersensitivity, cracked teeth or root fracture. Toothache caused by dental caries is because there is a cavity in the tooth. When it is stimulated by cold, heat, acid and sweetness or when food is embedded in the cavity, the toothache will stop immediately after the stimulating factors are removed. It is cold in winter, so it often causes toothache. The toothache caused by acute pulpitis is characterized by spontaneous and paroxysmal toothache, which is aggravated by cold and hot stimulation or rest at night. It is caused by deep cavities and deep periodontal pockets, and patients generally cannot clearly point out the position of the teeth. The toothache can last for a long time after the stimulation factors are removed, and the pain can be relieved after pulp opening surgery. Toothache caused by periodontitis is characterized by persistent dull pain, accompanied by gingival swelling, bleeding and purulent discharge, even tooth loosening and gingival atrophy; Toothache caused by acute and chronic periapical periodontitis is characterized by persistent jumping pain, teeth feeling elongated or floating, and unable to chew food.
In addition, diseases that can induce toothache include trigeminal neuralgia, osteomyelitis of jaw, dry socket, pericoronitis of wisdom teeth, acute suppurative maxillary sinusitis, malignant tumor of jaw, malignant tumor of gum, odontoid cyst of jaw, upper respiratory tract infection, heart disease, leukemia, hysteria, neurasthenia, etc., and symptomatic treatment should be taken.
The doctor specially reminded that the toothache caused by oral diseases is very uncomfortable, which is very irritating to people's health and spirit. General drugs or folk remedies can't cure it. The only effective way to stop the pain is to go to a regular oral medical unit for treatment.
