Khloe Kardashian is grinning from ear to ear after getting braces on May 9. Thanks to Kevin B. Sands, DDS, the 28-year-old Keeping Up With the Kardashians star got invisaligns to straighten her teeth.

"Thank you Dr. Sands for being the best dentist ever! If only we could all be put to sleep like [my husband Lamar Odom]," the reality star joked on Twitter. "Maybe next time!" Sands tweeted a picture with Kardashian May 10 and said it's "always a pleasure to have her and Lamar visit!"

Kardashian isn't the first celebrity to get braces later in life; Faith Hill, Tom Cruise, Gwen Stefani and Fantasia Barrino have each visited the orthodontist to straighten their teeth after becoming famous.

In addition to perfecting her smile, Kardashian is also hoping to change another aspect of her appearance: her arms. "They are the first place I'll gain weight and the last of the weight to go," she says in the June issue of Redbook. "I'm insecure about them, but there are ways to disguise them. I've learned to invest in cute cardigans. There are so many sheer and crocheted ones that are airy and you can still wear them with a little sundress."

The former X Factor co-host recently lost more than 20 pounds after modifying her diet and fitness routine. "I decided about six months ago to eat better and try to exercise regularly," she tells the magazine. "I love food. I'm never going to stop going out to dinner or enjoying a piece of birthday cake because I'm on a constant diet."
