1, tooth allergy
Toothache caused by drinking cold water may be caused by tooth allergy, which is usually caused by gingival atrophy, cervical dentin exposure and tooth defect. Patients with this disease will feel pain when they are stimulated by cold, heat, sweetness and acid, but the pain will disappear after the stimulation stops.
2. Deep caries
The caries of deep caries have reached the deep dentin, close to the pulp, or have affected the pulp. Patients feel pain in cold, hot, sour and sweet, and are particularly sensitive to heat, so there will be symptoms of delayed pain after drinking cold water.
3. Acute gingivitis
Acute gingivitis is a kind of gingivitis, and the damage is limited to individual gingival papillae. Acute inflammation occurs when the gingival papillae is stimulated by mechanical or chemical factors such as food impaction, improper use of toothpicks, sharp food stabbing, etc., which is manifested as redness, spontaneous swelling and obvious tenderness of individual gingival papillae, and even pain caused by cold and heat stimulation.
4. Chronic pulpitis
Chronic pulpitis generally does not cause severe spontaneous pain, but sometimes it can cause less obvious paroxysmal dull pain or regular dull pain every day. Chronic pulpitis has a long course of disease, and patients usually have a long history of cold and hot stimulation pain, so toothache and cold water may suffer from chronic pulpitis.
5. periodontitis
Periodontitis is mainly chronic inflammation of periodontal supporting tissues caused by local factors. Inflammation can spread from gum to periodontal ligament, alveolar bone and cementum, and develop into periodontitis.
Periodontitis is not obvious in the early stage, but when periodontitis develops to the late stage, the gums are oval, red and swollen, and even drinking cold water will hurt.
6, dental care instructions
1. Brush your teeth after meals.
Brushing your teeth immediately after meals can really remove food residues and tartar in time, but Australian dentists say that brushing your teeth immediately after meals will increase the incidence of tooth allergy 15%! Because there is a layer of enamel on the surface of teeth, the enamel on teeth will become soft after eating, especially after eating acidic foods such as fruits and dairy products. At this time, brushing your teeth will gradually thin the enamel, and over time, your teeth will be sour and swollen.
Strong tea is better than mouthwash.
Mouthwash can remove oral bacteria and purify the breath. But the latest research in Japan found that strong tea water tastes better than mouthwash! Catechols in tea can prevent and treat dental caries, and fluoride ions can also change hydroxyapatite in enamel into fluorapatite, improve enamel structure and greatly strengthen the acid resistance of teeth! Japanese medical experts also found that tannic acid in tea is an active ingredient, which can improve the oral environment and strongly resist carcinogens that may exist in the oral cavity.
3. Use less toothpaste, and your teeth won't hurt.
Most whitening tooth patches contain urea, hydrogen peroxide and other ingredients. According to the latest survey of the Canadian Dental Association, after long-term use of dental plaster, tooth allergy will increase by 25%, and oral soft tissue and gums will also be stimulated. Does drinking cold water hurt your roots? Maybe it's the whitening toothpaste!
Love him again, and don't use toothpaste with him.
Do you use toothpaste with your boyfriend? According to a survey, more than 80% of women now use a tube of toothpaste with their boyfriends, but Korean dentists say that there are many bacteria hidden in everyone's mouth. No matter how carefully you brush your teeth, you can't completely brush off the bacteria, especially the bacteria will attach between the bristles of the toothbrush. If you and your boyfriend use a tube of toothpaste, the bacteria in their mouths will gather at the nozzle of the toothpaste through the toothbrush, which greatly increases the probability of bacterial transmission. Therefore, sharing toothpaste and toothbrush is equally important!
5. Do not eat cold during menstruation, and your teeth are not red.
Still smug about not having dysmenorrhea at all every month? Put away your joy first and think carefully about whether you have oral ulcers during your period. Chinese medicine experts have found that more than 30% of dental diseases are related to women's neglect of menstrual maintenance. During menstruation, the level of qi and blood is low. If you eat a lot of cold drinks at this time, your immunity will be greatly reduced, and there will be temporary oral ulcers due to blood deficiency, such as slight redness and swelling of your lips and gums. Although ulcers will disappear automatically after menstruation, gingivitis will naturally find you over time!
6. Calcium supplementation is more important than eating less sugar.
The most practical way to protect teeth is to supplement calcium! More than 90% of hard enamel is calcium, which can protect teeth from corrosion. The slogan of American Stomatological Foundation is: Calcium supplementation is more important than eating less sugar! Although there are more and more toothpaste printed with the words "calcium supplement" on the market, the best way to supplement calcium is diet. Dairy products are the best calcium supplement food, and the effect is best when eaten at night, because the human body has the strongest ability to absorb calcium at that time.
7. Floss your teeth regularly.
American dentists say that even if you brush your teeth for up to 5 minutes at a time, 30%-40% of your teeth are not thoroughly cleaned, especially those with irregular teeth. The best dental care tool recommended by the International Oral Health Organization is dental floss, which can bring out the tartar in the "hidden place" and reduce the occurrence of dental caries. But don't keep using dental floss just because it works. Three times a week at most, or the gap between your teeth may be too big for you to laugh.
8. Love is the best medicine for toothache.
A sweet love mood can help you stay away from tooth decay. According to the latest report of the Center for Health Statistics in the United States, the number of T cells in men and women in a beautiful love relationship is maintained at the best state, and T cells have a positive effect on consolidating the oral immune barrier and resisting dental diseases. So if you have a toothache, stay with the person you love and let your happy mood help you cure it!
