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):

There are four different types of bleaching methods used in dentistry:
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:
for the first 24-48 hours.
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.
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 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.
