Well, I am actually having someone come fix it for me. But I have to do a few hours of online work, go shopping for food, and do my yoga routine before I have to go to the beach to train a kid at 4:30pm today. It is going to be really cold out but we are going to do the training regardless because he really needs the training and I really need the money! I bought some pricey purple teeth coloring whitener that is supposed to be like that for hair which removes the yellow temporarily. My HVAC expert buddy used it and his teeth were whiter the same day, if only for a few hours. But I don’t mind if it lasts a few hours, I’ll just use it again when I want whiter teeth. It’s called V34 and the local business near me sells it, and I plan on buying it as soon as this HVAC rep shows up to look at my furnace issue. I think the purple dye is a really creative idea for neutralizing the yellow color on teeth because that is how they do it for hair and it works great. I saw the difference in the heating dealer’s teeth, when I went in to buy a HEPA filter, and was like wow! My teeth aren’t crazy yellow but I want to give this stuff a try to see if it works as well as the reviews say. My hot water boiler is going to need some help after the central heating device is done, but one thing at a time.
