Hey, just wanted to throw out some info and another product suggestion.
I've always had problems with my teeth and gums. Lots of cavities. Last year dentist told me I have gum disease. Great. Fortunately it was at the early stages so I had them treated. I never knew why I had such bad teeth. Come to find out I've had acid reflux for YEARS (funny how you can have a problem and not know it). As others mentioned earlier, you think it's normal (yeah, normal to feel like you have a campire going on in your stomach). Needless to say acid reflux is murder on the teeth.
So anyway, this is something to consider on its own, and I suggest if you have been experiencing acidic tastes or heartburn, cut down on caffeine (or eliminate it altogether) and DIET SODA! Actually, all carbonated beverages and yes, beer will about double the acid in your stomach. Also avoid onions, peppers, and tomatoes.
But getting to the product, quite a few months I started using Stevia instead of Splenda as an artificial sweetener and noticed an improvement in my gums. They looked healthier, were 'pinker' in appearance, and I wasn't experiencing the intermittent swelling I used to get. This is while I was still smoking analogs, mind you. I read up on Stevia and it turns out the herb is known to be beneficial for teeth and gums.
A number of studies show that Stevia can be beneficial in the treatment of many health conditions. Stevia is believed to have anti-bacterial, anti-septic, anti-microbial, anti-oxidant, anti-glycemic, and anti-hypertensive properties which may help with hypertension (high blood pressure), diabetes, chronic fatigue, indigestion, upset stomach, heartburn, weight loss, cold and flu, gingivitis, tooth decay, cavities, dandruff and hair loss, brittle bones or osteoporosis, streptococcus, candidiasis, bacterial infections and skin conditions such as cuts, wounds, rashes, itchiness, blemishes, acne, seborrhoeic dermatitis, dermatitis, eczema, and wrinkles. It may also improve energy levels, strengthen immune system, stimulate mental activity, and may also help in withdrawl from tobacco and alcohol addiction.
Easy enough to add this to your diet if you are a tea or coffee drinker, or if you bake you can substitute it for sugar. Look it up yourself, it's an herb that has been used for many, many years.
