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.
However, treatment may take longer than it does for children. The average adult wears braces for 18 months to three years. As with children, adults may need to wear a retainer to maintain the results of treatment after braces are removed. The cost of braces depends on the type you select. On average, metal braces cost $5,000 to $6,000. Keep in mind that your out-of-pocket costs will likely be higher if you choose non-metal braces. Check your Evidence of Coverage, Summary Plan Description or Group Dental Service Contract to see if your dental plan covers orthodontic treatment for adults.
