Laughing Gas & Pain Free Dentistry …

At Whitefield we use Matrix USA Nitrous Oxide Inhalational Sedation System

Nitrous oxide is commonly known as laughing gas, nitrous, nitro, or NOS. At room temperature, it is a colorless, non-flammable gas, with a slightly sweet odor and taste. It is used in surgery and dentistry for its anesthetic, anxiolytic and analgesic effects. It is known as "laughing gas" due to the euphoric effects of inhaling it. Nitrous oxide, or laughing gas, was first used as an anesthetic for surgery patients over 160 years ago !

When administered, the body absorbs Nitrous oxide rapidly, allowing for both quick onset and recovery (two to three minutes). You will feel a bit light headed and often people get ‘the giggles’ (hence the name laughing gas!). In medicine, sometimes a mix of 50% oxygen to 50% nitrous oxide is used. This is known as entonox or, more commonly, “gas and air”. Depending on the concentration and length of administration of laughing gas,

FOUR LEVELS OF SEDATION can be experienced (after an initial feeling of light-headedness):

  1. 1. A tingling sensation, especially in the arms and legs, or a feeling of vibration (“parasthesia”),     quickly followed by
  2. 2. Warm sensations, and
  3. 3. A feeling of well-being, euphoria and/or floating.
  4. 4. At a deeper level of sedation again, sleepiness, difficulty to keep one’s eyes open or speak. YOU     MAY EVEN BEGIN TO DREAM. Should nausea set in, it means you’re definitely over-sedated!

Facts you should know Prior to receiving Nitrous Oxide Inhalational Sedation :

  • Please inform your treating dentist of any medical condition that your child might have.
  • If your child has a fever, ear infection or cold reschedule your planned dental visit.
  • Please inform your treating dentist of any drugs that your child is currently taking.
  • It is best to wear loose fitting, comfortable clothing while you bring your child for the dental visit.
  • Please make sure that your child uses the bathroom prior to beginning of the Nitrous Oxide Sedation.
  • Your child should not take solid food for at least 6 hours prior to his/her sedation appointment. However, he/she may have a clear liquid diet for up to 4 hours prior to the appointment.
  • The child’s parent or legal guardian must remain at the office during the complete procedure.
  • Your child will feel drowsy and may become slightly excited during the initial stages of the inhalation.
  • Your child will be drowsy and will need to be monitored very closely. Keep your child away from areas of potential harm.

Advantages of Nitrous Oxide induced sedation.

  • Nitrous oxide works very rapidly – it reaches the brain within 20 seconds, and relaxation and pain-killing properties develop after 2 or 3 minutes.
  • The depth of sedation can be altered from moment to moment, allowing the person who administers the gas to increase or decrease the depth of sedation. Other sedation techniques don’t allow for this. For example, with IV sedation, it’s easy to deepen the level of sedation, but difficult to lessen it. Whereas with laughing gas, the effects are almost instant.
  • Other sedation techniques have a fixed duration of action (because the effects of pills or intravenous drugs last for a specific time span), whereas gas can be given for the exact time span it’s needed for. It can also be switched off when not needed and then switched on again (though to avoid a roller-coaster effect, you shouldn’t do this too abruptly).
  • There’s no “hangover” effect – the gas is eliminated from the body within 3 to 5 minutes after the gas supply is stopped. Allowing you to self drive home!
  • For certain procedures – those involving gums rather than teeth (e. g. deep cleaning) – it may be possible to use nitrous instead of local anesthesia. N2O acts as a painkiller on soft tissues such as gums.
  • In cases of very severe needle phobia, getting laughing gas first can help you feel relaxed enough to allow the needle be inserted.
  • Inhalation sedation is very safe. It has very few side effects and the drugs used have no ill effects on the heart, lungs, liver, kidneys, or brain.
  • Inhalation sedation has been found to be very effective in eliminating or at least minimizing severe gagging.

Teeth Whitening: Facts you probably already know…

[Whitefield Dental Clinic Abu Dhabi – Facts on Teeth Whitening, Nov 2013©]

There are four different types of bleaching methods used in dentistry:

  1. A. In Office Bleaching- PowerAssisted.
  2. B. Home Bleaching
  3. C. Combination of A & B
  4. D. Walking Bleach

All bleaching happens through oxidation or reduction of stains by the chemicals in the bleaching agent. The key component in all bleaching agents is active hydrogen peroxide which when activated releases nascent oxygen.

All bleached teeth at some point reverse to their natural baseline color. This reversal may take six to nine months or could be prolonged with proper care. Such as follow up home bleaching, use of whitening tooth pastes and most importantly avoiding stain producing habits or diet.

After whitening (bleaching), teeth becomes dehydrated temporarily, making them more susceptible to picking up stains all over again. In order to prevent this we advise our patients to avoid consuming dark staining food types, such as:

  • Coffee
  • Tea
  • Colored medications
  • Syrups
  • Carrots
  • Tomato sauces
  • Soy sauces
  • Carbonated drinks
  • Red wine
  • Tobacco, etc

for the first 24-48 hours.

  1. Coffee will stain the teeth easily!
  2. A small bag of carrots or celery after coffee or tea prevents staining
  3. Drink Coffee Cooler

Yes! Consumption of coffee, particularly black coffee within the first 24-48 hours after a bleaching session will stain the teeth easily, therefore should be avoided. However, the stains thus gained are not permanent and can be removed easily by your dentist.

Tips on continued care:

A small bag of carrots or celery after coffee or tea prevents staining. These vegetables contain a lot of water that helps to rub off stains between the teeth and remove any other unwanted food from teeth. The fiber content within these vegetables, in addition, works as a scrub to remove macro stainproducing elements from the surface of the teeth.

Drink coffee cooler.

Unfortunately this is the truth! The hotter the coffee, the easier it will stain your teeth. Why? Because very hot drinks can cause minor cracks to develop your teeth or expand already existing ones- staining components attach to them easily. Even only a couple of degrees cooler can make a difference.

Flavonoids are
most commonly
known for their

than green

For the geeks

Flavonoids are widely distributed in plants.

Flavanoids are the most important plant pigments for
flower coloration producing yellow or red/blue pigmentation in petals designed to attract pollinator animals.

Flavonoids are the most common group of polyphenolic compounds in the human diet and are found ubiquitously in plant. Flavonoids are most commonly known for their antioxidant activity. Although physiological evidence is not yet established, the beneficial effects of fruits, vegetables and tea or even red wine have sometimes been attributed to flavonoid

compounds rather than to known micronutrients, such as vitamins and dietary minerals.

Flavonoids in my coffee? Health Guru’s are always talking about green tea or chai latte! Well you will be happy to know that coffee actually contains more antioxidants than green tea. Chlorogenic acids, for example, are strong antioxidant compounds found in coffee.

Coffee also has two to three times more phenolic acids than tea.
