What should I do if my teeth ache due to hot or cold weather?

In our daily life, we may suddenly find that our teeth feel pain when they come into contact with hot or sour foods. This symptom may be gingivitis or periodontitis. For dental diseases, they need to be treated early if discovered in time.

Teeth hurt when exposed to cold or heat, and bleed when brushing. Pain when teeth are exposed to cold or heat is generally a symptom of chronic pulpitis, and your tooth has been filled, so it is impossible that the cold or heat entering the caries cavity causes pain. Generally, acute pulpitis cannot be located, but chronic pulpitis can be located. So I think the doctor's diagnosis of the disease may be wrong, or the caries has not been completely removed, and the remaining caries continues to develop and cause pulpitis, but this possibility is extremely small, because it has just been filled for a month, and it is still a chronic symptom.

Bleeding gums are generally typical symptoms of gingivitis and periodontitis, but first you must rule out blood diseases such as leukemia and hemophilia, which are prone to spontaneous bleeding. If bleeding is caused by mechanical stimulation such as eating, brushing teeth, etc., then it is gingivitis and periodontitis. The reason is the driving factor that causes the disease - dental plaque. Although you have a strong awareness of oral hygiene, it may be related to your improper brushing method and your host susceptibility. The only treatment for pulpitis now is root canal treatment, which includes killing the nerve (or extracting the pulp directly with anesthesia) - extracting the pulp - cleaning the root canal - disinfecting the root canal - filling. This process is called root canal treatment.

The treatment of gingivitis must first remove dental plaque, tartar and other pathogens, which requires teeth washing and subgingival cleaning. Then, pay attention to maintaining oral hygiene and pay attention to brushing methods twice a day, morning and evening. Teach you how to brush your teeth: Choose a soft-bristled toothbrush, point the toothbrush at a 45° angle to the long axis of the tooth toward the apex (upward for maxillary teeth and downward for mandibular teeth), press the gum-tooth junction area, allow part of the bristles to enter the gingival sulcus, and part to spread on the gingival margin, and extend as far into the interproximal space as possible, use gentle pressure to make the bristles vibrate horizontally in the original position for a short distance in the front-to-back direction 10 times. When vibrating, the toothbrush moves only about 1 mm, and brushes 2 to 3 teeth each time. When moving the toothbrush to the next set of teeth.

Pay attention to overlapping placement. If the dental arch is narrow on the lingual and palatal side of the front teeth, hold the toothbrush vertically, press the bristles into the gingival sulcus and interproximal space at an angle of about 45°, and make short vibrations against the long axis of the tooth. The brushing action for the occlusal surface is to press the bristles tightly against the occlusal surface, so that the bristle tip penetrates deep into the gap, and vibrates in the direction of the front and back teeth.
