Dental Injections To Fear or Not to Fear!

If you’re anything like me, dental injections look more like horse tranquillisers than ‘local anaesthetics’. However when you really think of it we should be grateful for these injections. Think of Tom Hank’s character in the movie Cast Away. He had severe tooth pain when he was stuck on that Island and no dentist near by. He took out his tooth without an anaesthetic and was knocked out for hours from the pain itself. I remember telling myself never ever will I fear the dental injection. So let's take a closer look at the thing we fear the most in the dentist chair.

Is dental injection painful?

The biggest question that we ask … Does it hurt? When you compare it to the pain you’ll feel without it, its very minor. Most people don’t feel any injection pain other than a little sting which isn’t a result of the needle itself but more of the solution working itself into the area .Your dentists primary focus is to make sure you as a patient feel very minimal discomfort during the procedure.

What to expect

Your dentist starts off by drying the area of your mouth with air or cotton and then applies a topical anaesthetic (numbing gel) onto the gum prior to any work done to decrease the pain. When your dentist inserts the needle, they insert the anaesthetic slowly and in small steps. They add extra drops of anaesthetic in front of the direction the injection is going to take and continue injecting into the tissue that is already numb which decreases your chance of feeling the pain. This means the slower the injection rate of the solution, the less pain.

There are two different types of anaesthetic injections. The first one is a block injection which usually numbs the whole area of the mouth and is usually inserted into the lower teeth. The other injection is an infiltration injection which numbs a smaller area and is usually used on the upper teeth. The anaesthetic takes 3 to 5 minutes to be in full effect and lasts up to several hours after you’ve left the dentist.

What are the side effects of dental injections?

Side effects are rare as this is the most common drug used in the dental industry. Whilst it is rare to have an allergic reaction to the local anaesthetic, always remember to tell your Dentist of any medications you are currently on or any allergies you have or have had in the past. It’s all about trusting your dentist and having an honest connection with them. Visit your local dentist in Melbourne CBD and eliminate that fear of local anaesthetic injections ASAP!

Dental Injection, the word "injection" can conjure up some pretty scary images for most people: needles, needles, and more needles. But dental injections aren't anything quite like the disastrous scene from the movie "Orphan". They're just a form of local anesthesia or medicine that numbs the body so it doesn't feel pain during some procedures. It's a technique that's been used for years, and it's quite simple to perform.

Dental injections are a way to treat pain caused by tooth decay without breaking the tooth or disturbing the gums. The procedure involves placing a fine needle into the tooth. Which will be numbed and then injected with a local anaesthetic. The injection can be used to treat many types of tooth pain and related problems. Such as a cracked tooth or a pulp abscess.

Pain caused by dental problems is especially difficult to deal with. Many people avoid dental treatment because they are afraid of the pain. That said, dental treatment does not have to be painful. Painless dental injections are available to help alleviate pain. The dental treatment process can be difficult and frightening for some patients.
Painless dental treatment can be as simple as injecting local anaesthetic through the gums. Directly into the tooth or the surrounding nerves.
In some cases, the injection is made into a pocket within a tooth. Which can be a very effective and safe pain-reduction option.

Injection - How Numbing Agents Works

Dental Injections Site : One regrettable but necessary part of going to the dentist. Some procedures like extractions or even dental fillings will require you to get a needle. This is why dentists sometimes will give what is called anaesthetic, used to numb your teeth. Numbing agents might come in the form of a paste they put on your gums or they might even give you a needle.

Dental injection numbing gel works to numb the tooth and surrounding area. It helps so you won’t feel any pain during the procedure which allow dentists to get the job done swiftly. However, sometimes this can cause other areas around the injection site to be numb as well, which might be quite a funny feeling. This can include your tongue, lips, cheeks, nose, etc. But not to worry! Local anaesthetic stays in the system for 24 hours. However the numbing feeling will generally go away after in about 45 minutes to an hour.

Do not eat after getting a local injection at the dentist

Dental injection, so you are numb. That means you can poke, prod and bite these parts of your mouth without feeling any pain. This can be dangerous, especially for children. Because you can damage your mouth without even knowing it.
After getting numbing at the dentists, be very careful not to accidentally bite on your lips, cheeks or tongue. As well, it’s important to watch your children and educate them on what is happening after the procedure to prevent any damage. It can be helpful to avoid eating/chewing until you regain feeling.

If taking pain medication, it’s advised to take some right after the procedure. Pain killers take about 30 minutes to take effect. Remember the pain relief from anaesthetic wears off in about 45 minutes. Hopefully this information will help you all have a smooth and painless transition from dental surgery to recovery.

The road to a beautiful smile is more than just a visit to the dentist. It's a road paved by patience and commitment, and luckily it's one that almost everyone can travel.
