In dentistry, tartar is calculus build-up that occurs on the teeth.
Yes, tartar is the correct spelling if you mean the build up of material on your teeth or a sauce for food. It is however tartare if you are referring to the raw meat dish, Tatar if you mean the original people of Russia, or tarter if you mean more tart (bitter)
Tartar is hardened plaque. Plaque is the soft film on your teeth when you eat , or just get up in the morning, and you can just scrape or brush it off. Sometimes you can't get it all. After a while it turns really hard and has to be removed with an instrument called a scaler. It has sharp edges that can scrape it off safely.
Teeth
The hardened deposits that form on the teeth and can irritate the surrounding tissue, is called tartar or dental calculus. If good oral hygeine is not practiced, tartar can build up on the teeth and become hardened. This can irritate the gums and cause them to bleed.
Tartar eventually builds up and remaining residue from food, etc. cannot be fully rinsed from the mouth by saliva only (saliva is actually the mouth's main sanitizer). This can eventaully lead up to gingivitis and cavaties since there is a bacteria build up. It's always a good idea to brush twice a day: in the morning and before you go to bed!
Cream of tartar is a byproduct of winemaking and contains potassium bitartrate, but it does not contain alcohol. While it can be used in cooking and baking, consuming cream of tartar will not lead to intoxication. However, excessive consumption can cause digestive issues due to its high potassium content. In summary, you cannot get drunk off cream of tartar.
