Opinion
There is a saying that, if you do not like something, change it. A smile is one of the most important things in a person’s appearance, it shows their mood and it is huge confidence booster.
People work on their smiles all the time, many people had to wear braces for months or even years, some get veneers just so they can have great smiles and not avoid smiling or not have the confidence to smile.
Spending money on improving a smile is always a good investment and a huge confidence booster.
