Plaque can be removed with baking soda, salt and orange peel oil. Coconut oil is also used to remove plaque and, when used regularly, to prevent tartar buildup.
To remove plaque with salt, baking soda and orange oil, mix equal parts salt and baking soda, and apply the mixture to a toothbrush. Squeeze a fresh orange peel onto the toothbrush to release several drops of the moisture inside the peel, then brush as usual. Baking soda and salt are mild abrasives that scrub the plaque away, while orange oil works to soften and remove both plaque and tartar build up. Limit the use of baking soda and salt to once a week to prevent damaging the enamel.
Coconut oil has antibacterial properties and is used to remove plaque by swishing the oil around in the mouth. This is thought to be an effective method of killing bacteria in the mouth, which reduces plaque and tartar. To use this method, put 1 tablespoon of coconut oil in the mouth and allow it to melt. Swish the oil around for up to 15 minutes before spitting it out. It can also be used during regular brushing by mixing with baking soda or regular toothpaste. Oil can be used as often as desired.
