You should NOT brush your teeth with Comet!
Comet should not come anywhere near your mouth or eyes.
The chemicals in the Comet are not meant to be used internally (or externally, for that matter). They are poisonous and possibly fatal, if ingested.
Use toothpaste. If there is none, then dampen your toothbrush with water, and sprinkle a little baking soda onto the bristles. This will NOT harm your body, it will clean and whiten your teeth. It doesn't taste very good, but after you rinse your mouth with water you will enjoy the freshness.
You should take your cat to the vet immediately just to be safe.
No. While some people may have a body that is more resilient to Comet, the body still considers it a toxin. If enough of it gets in your system (it sometimes takes a while for your body to get rid of toxins), it can over come your immune system and make you sick
It is abrasive and will irritate your hands and possible, after several uses, burn your hands. Regular soap and water is cleansing enough. Be sensible.
Hydrogen peroxide is most commonly used as a gargle agent rather than a toothpaste.
Gonzo Glomgold probably doesn't brush his teeth with gunpowder because it's not safe or healthy. Gunpowder is highly explosive and not meant for dental hygiene. It's important to use toothpaste and brushes specifically designed for cleaning teeth to maintain good oral health.
No, borax is not safe for brushing your teeth. It can be harmful if ingested in large amounts and is not intended for oral use. It is important to use toothpaste that is specifically formulated for dental hygiene.
A great, gentle cleanser is Pro-Activ. It is great for normal skin, but will not break out sensitive skin. It is safe and approved by a lot of dermatologists. Check out www.proactiv.com
Read the ingredients on the tube. Toothpaste does not contain lactose. And you are supposed to brush your teeth with it, and spit it out. Toothpaste Is not intended to be eaten.
Clorox just came out with a cleanser that is safe
Yes.
Elemis cleanser is actually a facial cleanse. I do not believe it is recommended to use it to clean porcelain. I have not been able to find any information saying that it is safe for porcelain.
No, you should never use human toothpaste on a cat, as the fluoride alone is toxic and can make a cat ill if ingested. If you wish to brush your cat's teeth, use a pet toothpaste that has no fluoride in and is safe to ingest (I cat cannot spit out toothpaste like humans do).
