It is a dental treatment in which a dentist removes a tooth from your mouth. It is also known as the “pulling of tooth”.

Dentists or surgeons check whether the patient can have root canal therapy rather than a tooth extraction. Tooth extraction has some risks and the hole in the bone from where the tooth is pulled. The symptoms for which the dentist performs tooth extraction are tooth decay, tooth injury, and infection in the gums. 

10. What Is Root Canal Therapy? What Is Its Alternative?

When bacteria enter the pulp, they infect our teeth. Root Canal Therapy is performed to save the infected teeth. Dentists use this treatment to eliminate the infected pulp from the tooth and then fill the cavity. It saves the natural teeth from frequent infection. The symptoms like swelling of gums, pain in the tooth while chewing, and discoloration require Root Canal therapy. The alternative to Root Canal Therapy is Tooth Extraction. In tooth extraction, the tooth is extracted, but in the root canal, the natural tooth is safe by removing the infected pulp. It depends on the patient which treatment is suitable for him. 

11. What Is Dental Pulp And Why It Should Be Removed?

The dental pulp is the soft part between the teeth. It is composed of connective tissues, nerves, and blood vessels. These provide the nutrients to the teeth for proper functioning and development. There can be many reasons for the dental pulp to be removed. When the infections enter the pulp via damaged nerve tissues, it infects the tooth.

If a person finds these symptoms, he should visit dental health care to treat them as early as possible.

Air abrasion is a technology that provides a drills-less way to remove tooth decay. In this process, we spray on the infected part. The spray contains aluminium oxide or silica. It slowly removes tooth decay. It is also used to prepare the tooth for filling and to remove the decay stain from the tooth. Air abrasion is safe, but the spray can cause eye irritation. But there are some disadvantages of air abrasion. These include not being suitable for deep cavities, only being suitable for the small cavity, and cannot remove access tooth decay.  

14. Do You Thin The Dental X-Ray Is Safe?

Dental X-rays are safer than exposure to other radiations. The amount of radiation in dental X-rays is kept small, so it can not harm the patient as other radiations do.

15. Tell Us The Steps To Disinfect The Dental Equipment?

The dental equipment must be handled carefully for their safe and proper functioning.

It is used in conditions like the base for the cavity, for baby and children’s teeth, and for front teeth.

Gingivitis or flamed gums is caused by the formation of plaque in the gums. It is a very serious condition, and if not treated can cause periodontitis which is jaw bone disease. The diseases like Scurvy and Leukemia may also lead to bleeding gums. Some other causes include deficiency of vitamin K, brushing hard, bleeding disorders, and tooth or gum infections. 

23. Do You Think Alcohol Affects Dental Health?

Alcohol contains sugar content which indirectly forms acid in the mouth. It causes tooth decay. The more sugar content, the more tooth decay. Alcohol dries out the mouth, which stops the saliva flow. The saliva is essential for the oral cavity and prevents bacterial decay. At last, Alcohol contains many hues which turn the teeth color and decolorizes them for a long time. So, if you are having a drink, you should take one which less sugar content and drink a glass of water to normalize the saliva.

  • X-Ray?

There is a need to perform a dental X-ray of the patient to find out the dental health of the patient.
