I agree that stainless steel is bad for coffee (glass-vacuum carafes are cheap and effective), but it usually takes awhile, an hour or more, before I notice a significant change in flavor from exposure to steel. On the rare occasion that I cannot avoid using a travel mug, I use this thermos tumbler.
Braces cost is around $4000-$6000. Braces cost $3,000-$10,000 depending on location and also on what kind of dentist does them, general dentist (cheaper) or orthodontist (more expensive). In European countries Braces usually cost about $5,000 nowadays.
These braces will be worn for a shorter period of time as they do work quickly, but they are more expensive than metal braces thanks to the technology and they are still very visible when compared to more subtle treatments like Invisalign. Expect to pay between Â£2,000 â Â£3,000 for smart bracket braces.
