Dental Treatment for Brisbane’s Most Anxious Patients with Laughing Gas

Anxiety towards dental treatments is often experienced both by children and adults. Dental anxiety can happen before simple procedures like injections or traumatic procedures such as tooth extraction. Perhaps anxiety is inevitable in dental surgeries. Sedation is used in many dental clinics to manage and reduce dental anxiety. “Sedation makes an anxiety-provoking situation more tolerable”, Brisbane Dentist. Small doses of happy gas can induce a pleasurable feeling and assist anxious patients in better tolerating a moderately painful treatment.

Pain-Free Dentist Brisbane

Anxious Patients May Cry Because They Have No Other Choice. Compared to children, adults can better repress their feelings and anxiety but probably adults are as anxious as children when it comes to injection or tooth extraction. Adults have the option of avoiding, procrastinating or cancelling their dental appointment whereas children do not have this option, therefore they show their anxiety with crying, etc. click here to see how you can deal with dental anxiety in children.

Sedation techniques in dentistry are not absolutely pain-free, however, there are techniques that dentists use to manage pain and anxiety in patients. Laughing gas dulls pain and helps reduce anxiety. It does not provide a 100% pain-free sedation when you are experiencing significant pain. In addition to laughing gas, your dentist may also use local anaesthesia (numbing medication) in your mouth to achieve better results.

Sleep Dentistry

Laughing gas helps nervous patients relax in the dental chair during their procedure. Your dentist administers controlled amount of laughing gas so that you stay conscious and able to follow dentist instructions. Laughing gas is a conscious sedation but some patients incorrectly refer to it as “sleep dentistry”. Generally, laughing gas administered during dental treatments, does not prevent you from driving after the procedure is fully complete. Laughing gas tends to wear off quickly as soon as the gas valve is closed. But check and communicate with your dentist if you are ok to leave 5 to 15 minutes after your treatment is complete.

Pain Relief: Care for Anxious Patients in Dental Pain

N2O, also commonly known as Laughing Gas, Happy Gas, Magic Air or Sweet Air, is a sedative with a safe application history of nearly two centuries. Since its introduction, laughing gas has remained a popular sedation option. When used safely, it can kill or reduce dental pain. Laughing gas is administered by inhalation in conjunction with oxygen.

Happy Gas for Tooth Extraction Pain Relief

Laughing gas has been used as a sedative in dentistry since 1844. Some dentists used this gas to control pain during tooth extraction. Patients normally feel a euphoric feeling spread throughout their body approximately after about 5 minutes of inhaling the gas. Happy gas has pain-reducing effects and cannot kill significant pain. It assists with the acceptability of unpleasant procedures.

Laughing Gas is Needle-Free and Quick

Happy gas is an appealing procedural sedative for patients with significant needle phobia because it is applied without needles and has a rapid onset and recovery which is an ideal characteristic for a sedative. In dentistry, laughing gas may be used to provide moderate sedation for procedures that are minimally to moderately painful.

The needle-free application of the laughing gas can be used to mitigate needle phobia in some patients. It can also make patients more receptive of being injected. In fact, many people who are sedated by laughing gas inhalation, often won’t remember being injected during the procedure.

Unlike other sedatives used by dentists e.g. Lidocaine, laughing gas starts working quickly after the patient begins to inhale it. The gas also wears off just as fast once it is removed from the patient. After your treatment under laughing gas, you can check with your dentist to see if it is OK to drive or not.

What Does Laughing Gas Do

When laughing gas is inhaled alone it can cause euphoric effects. When administered as a mixture with oxygen, it puts the patient in conscious sedation. Laughing gas is not intended to put a dental patient into sleep.

The mixture of Laughing gas with oxygen (Laughing gas/Oxygen mixture) has sedative properties.  The mixture is inhaled normally through a nose mask. When a safe and controlled amount of the mixture is inhaled, patients can feel relaxed and sedated. After breathing the gas, within a few minutes, you may feel heaviness or tingling in your legs and arms. You may also feel light-headed. Eventually, you should feel calm and comfortable.

Unsafe amounts of laughing gas can be harmful, cause hallucination and death. Dentists use a machine to deliver safe amounts of the mixture which is required for conscious sedation. Within a few minutes after the laughing gas machine is shut off, the gas is breathed out of the patient’s lungs. Laughing gas has low solubility and therefore exists rapidly from the body.

Can You Still Feel Pain with Laughing Gas?

Laughing gas can kill slight and moderate levels of pain. It is used to reduce or ease pain. Injection for example, is not considered an extremely painful procedure. Some patients may not notice injection when sedated with happy gas. Laughing gas cannot kill significant pain.

What are the Risks of Laughing Gas

There is always risks of complications from getting anaesthesia.  Consult with your doctor prior to taking sedation if you are obese or you have obstructive sleep apnea.

To reduce the risk of nausea and vomiting keep your meals light before dental treatment that include laughing gas administration.

Dentists avoid the use of laughing gas sedation for pregnant women during the first semester of pregnancy to prevent any potential risks to the newborn.

Side Effects of Dentist Laughing Gas

Most people do not experience any adverse side effects, but a small number of people do. Your dentist controls the required dose and the timing of the application of the gas. The most common side effect that people may experience with Laughing gas is nausea and vomiting. some studies have linked deep and long sedation with nausea and vomiting.

Other negative side effects of dentist laughing gas include:

  • Headache
  • Increased Sleepiness
  • Excessive Sweating
  • Shivering

If the sedated patient does not receive oxygen for at least 5 min after the laughing gas has been shut, headaches can result. In oral surgeries with laughing gas, dentists use a machine to deliver a happy gas/oxygen mixture to the patient to inhale. The patient is kept conscious so they can respond to dentist instructions.

Laughing gas irreversibly oxidizes vitamin B12 in people who are chronically exposed to trace amounts of the gas. Chronic exposure reduces the activity of B12-dependent enzymes including methionine and thymidylate synthetases.

If you decide to use laughing gas, advise your dentist if you have any of the following conditions:

  • If you are Pregnant
  • If you have Chronic Obstructive Pulmonary Disease (COPD). COPD is a type of obstructive lung disease. COPD is characterized by long-term breathing issues and poor airflow.
  • If you have Methylenetetrahydrofolate Reductase Deficiency. (MTHFR deficiency may cause intellectual disability, psychosis, weakness, Ataxia, Spasticity and Homocystinuria due to high levels of homocysteine in the blood)
  • If you have Cobalamin Deficiency (low blood levels of vitamin B12)

Also, if you are using Bleomycin Sulphate (Bleomycin Sulphate is used to treat Cancer) or have a history of emotional issues or drug addiction, laughing gas may not be suitable for you.

Pain Free Dentist Brisbane Southside

It is hard to say if pain-free dentistry exists. People have different pain thresholds. The injection can be tolerable for some people and intolerable for others. Laughing Gas can dull pain and calm people with dental anxiety. But it cannot be 100% pain-free. Laughing gas (also called happy gas) is colourless and slightly or somewhat sweet in taste and smell. In the past 180 years, happy gas has been used by dentists as an anaesthetic (something that induces insensitivity to pain).

Laughing gas was discovered in 1772. People would pay to breathe in tiny amounts of happy gas to laugh. The application of happy gas in dentistry goes back to 1844 when a man who had a bad cut and had breathed in laughing gas sat next to a dentist and told the dentist that he could not feel any pain and he did not know he had a cut. That dentist was dr. Horace Wells, an American dentist who found that laughing gas can dull pain. He applied laughing gas to dentistry. To demonstrate the application of laughing gas in dental treatments, he had his own tooth removed while inhaling happy gas.

It is only effective with moderate levels of pain e.g. injections and mild dental surgeries like tooth extractions, etc. it is also effective in calming patients who are anxious about their visit to the dentist.
