Myth vs. Fact Myth: If the appearance of my teeth doesn’t bother me, there is no point in getting braces or Invisalign.

Fact: Whether or not one should seek orthodontic care at an older age is an individual decision. Many people live with crowding, overbites or other types of alignment problems without the motivation to seek orthodontic treatment. However, many people feel more comfortable and self-confident with properly aligned, attractive teeth. Unlike strictly cosmetic procedures, orthodontic care can also benefit your long-term

dental health. Straight, properly aligned teeth are easier to maintain with proper oral hygiene, such as flossing and brushing. This can help reduce the risk of cavities as well as gum disease, which occurs more readily as it becomes increasingly more difficult to clean around crowded and rotated teeth. In addition, people with bad bites may chew less efficiently.

“Keeping it flossy since 2007”

Answer to DAT Practice Question: 1-Methylcyclohexene reacts with strong aqueous acid to

produce (b) 1-methylcyclohexanol In this reaction, the electron-rich C=C bond of 1-methylcyclohexene accepts a proton from the strong acid solution forming a C-H bond between one of the C=C carbon atoms and the H+ ion. This results in the formation of a 2 carbonium ion at C2 if the C-H bond forms on C1 or a 3 cabonium ion at C1 if the C-H bond forms on C2. The process is a reversible equilibrium, and since a 3 carbonium ion is more stable than a 2 carbonium ion, any 2 ions formed would rearrange to the 3 ion structure. Addition of H2O to the carbonium ion, followed by loss of H+, produces the product 1-methylcyclohexanol.
