Tongue problems...well...here we go.
You posted, "I have developed these splotches on my tounge, at first I thought they were blisters but they do not hurt nor will they go away."
I need a little more detail on the splotches.
How big are they? (pin head, dime, quarter)
How many? (one, three, five or more)
Are they the same size?
Do they look smooth or rough?
Red, white or mixed red and white?
What does the border around them look like?
Are they painful or sensitive when you eat/drink acidic or spicy?
Do they appear to move around get larger or smaller?
How long since you first noticed them?
Ok, if you can answer the above I may be able to give you some ideas.
Cleaning the tongue is something everyone should do as well as, cleaning the cheeks and roof of the mouth. You can buy many different brands of tongue scrapers and rinses but they are really unnecessary if you do the following; (if a retail product motivates you to be more diligent then go for it but, it is unnecessary. A toothbrush works fine.)
Floss your teeth properly and gently, brush your teeth methodically (gently) making sure you clean all of the surfaces and massage the gum gently with your toothbrush. If the bristles on your toothbrush look like this after three months or less, "\\\///", you are using way too much pressure when you brush. Rinse your mouth out with a non-alchol oral rinse vigorously for 2 minutes and spit it out. Stick your tongue out and with gentle strokes brush your tongue from back to front. After every stroke rinse your toothbrush. When you have covered the whole tongue do the same with your cheeks and palate. After you have accomplished all of this rinse with a neutral sodium fluoride rinse for approx. 2 minutes and spit it out. Don't eat or drink for thirty minutes to allow the fluoride to penetrate the enamel.
Don't expect that the first time you perform this that your tongue will apear pink and clean. The pappilae have crevices and it may take a few days of following this routine to fully cleanse them. If it hurts you are doing it wrong and if your tongue bleeds your are doing it wrong. Don't try and go to the back of your throat and gag yourself or worse start puking.
The rinse can be salt and water if you like, 1/2 teaspoon of salt in 1/2 cup of warm water is all you need. More salt doesn't make it any more effective. CAUTION: If you suffer from high blood pressure or heart disease or have been told to limit your salt intake you should use salt and water rinses sparingly. The direct capillary absorption under the tongue can cause problems in individuals with these conditions.
I hope this helps.
