1, the cause of toothache
What is the cause of toothache?
Because there are nerve fibers scattered in the teeth, so when the teeth were damaged, the nerve tissue of the teeth was indirectly or indirectly stimulated, passed to the center, people will feel toothache.
The body of the tooth is the tooth itself, including tooth enamel, tooth substance, tooth bone three calcified hard tissue and a soft tissue composed of dental pulp. Dental substance constitutes the main body of the tooth, dental enamel covered in the crown appearance, dental bone covered in the root appearance, there is a cavity in the center of the pulp cavity, pulp cavity within the pulp tissue, the blood vessels and nerves through the narrow apical foramen and periodontal tissue contact. Dental parenchyma has a clear response to external mechanical, temperature and chemical stimuli. There are nerve fibers in the dentin tubules.
The feeling transmission of the dental parenchyma is common for the external stimulus indirectly stimulate the nerve endings of the dental parenchyma, and then transmitted to the center, or the external stimulus provokes the activity of the contents of the dental parenchyma tubules, indirectly make the pulp of the dental parenchyma at the border of the nerve endings to be agitated (the flow of brawn hypothesis), or the tooth cell protrusion stimulated by the transmission of the cell body to the body of cells to provoke the cell body of the outer surface of the electric charge changes and affects with the contact of the nerve endings.
And the pulp cavity is very rich in nerves, from the alveolar nerve branches with blood vessels from the apical foramen into the pulp, and then divided into many fine and finer branches. Most of the nerves entering the pulp are medullary nerves, which conduct pain, and a few are unmedullary nerves, which are sympathetic nerves that regulate the contraction and diastole of blood vessels. So when a tooth injury injures the parenchyma and pulp, the patient will feel a distinct toothache.
2, toothache emergency pain relief method
First: dental trauma: such as accidental falls, bruises, or bite into the sand when eating, etc. to the tooth fracture or cracked teeth, resulting in toothache. You can take anti-inflammatory, painkillers and go to the dentist immediately.
Second: caries: the first caries is generally asymptomatic, such as caries holes become larger and deeper, there can be a toothache when eating, eating sweets or too cold, too hot food when the pain is aggravated. At this time, you can first use anti-acid pain toothpaste, warm water brushing, the fundamental treatment should be to fill the caries hole.
Third: pulpitis: mostly due to deep caries not fill the pulp infection, chemical or temperature stimulation caused by the pain for spontaneous, paroxysmal pain, cold, hot stimulation pain and knocking pain. Emergency treatment of this kind of toothache, can be used fenpropidol 300mg orally, 2 times a day.
Precautions: patients with a toothache that is not very severe can take some anti-inflammatory drugs, but long-term reliance on anti-inflammatory drugs to relieve pain is not long.
3, teeth whitening methods
(1) Strawberry teeth whitening
Strawberry teeth whitening is mainly for exogenous staining. Strawberries contain an enzyme that removes stains from the surface of the teeth. Mixing strawberries with baking soda, breaking them up and brushing your teeth can help eliminate stains.
(2) Scaling
Scaling is mainly done in the hospital with instruments to remove surface stains and polish the tooth surface, also mainly targeting the enamel to make the teeth look white and shiny. Scaling is equivalent to cleaning in our daily life, wiping away the dust and keeping the surface clean.
(3) Photosensitive Veneers
Veneers are a layer of tooth-colored material bonded to the surface of the teeth to cover the unsightly color of the teeth, thus making the teeth look white. They are inexpensive and easy to apply.
(4) Bleaching
Bleaching, as the name suggests, is the use of hydrogen oxide and other bleaching agents to bleach the teeth. However, bleaching agents can penetrate the enamel, affecting the dentin and even causing damage to the pulp. So you should be careful when choosing a bleaching treatment.
