The main work of dentists is to take out the decay tooth or repair some oral tissues. This work can causes pain to patients as a result, doctors use anaesthesia to lessen the pain during operation. They inject the needle in some gum or nerves to numb it. And therefore it may cause some side effects which may be harmful to patients.
Some of the Dental Anesthesia advantages are
Pain free surgery:- The patient not at all feels the pain when operation is going on. As a result dentist work completely smoothly.
Some Dental Anesthesia Disadvantages are
Swelling:-Local anaesthesia causes swelling around the area where drug is injected. If it hit some nerves or blood vessel then it causes swelling in that region.
Heart beat faster:-Local anaesthesia results in increasing the heart beat because patient feels anxious while the drug is given.
Allergies:-Sometimes some drugs may react with anaesthetic solution that causes allergies to the patients. For this dentists should be careful keeping the medical records in mind.
Costly:-The process of anaesthesia and all dentist process can be costly for some people that’s why people avoid to take anaesthesia drug.
Dental Anaesthesia has some side effects and it can show its adverse effects if proper precautions are not taken
The basic side effect is hematoma. In this if the needle is injected that might puncture or damage some blood vessel that may result in clot under the surface of skin in the mouth or may affect some gum. The chances of swelling may take place which may be dangerous. Basically this swelling dissolves within 7-10 days without any treatment.
Another side effect is paresthesia which causes numbness around the eyelid and near mouth. This makes it difficult for the patient to eat or to chew. The patient should be careful while moving his mouth. Sometimes it causes tingling effect all over the body, but this effect automatically disappears within few months.
Another side effect is CNS Toxicity. When a drug is injected in the skin of the patient it rapidly mixes with blood stream which can affect brain resulting in toxicity of the central nervous system. This results in increase in heart beat and difficulty in breathing. In severe cases sweating and paleness increases.
Another side effect is hypoxia, which means supply of oxygen is less and very low oxygen to the brain. This may result in dizziness to the patient. In severe cases patients may have anemia.
The basic side effect is prolonged numbness. Generally anaesthesia is given for few minutes or hours for completing the surgery. But sometimes this numbness extends to few days or months. This results in patient bite his tongue or lips. In extreme cases this numbness becomes permanent.
