I'm sure this protruding look must have been bothering you. Protruding teeth do prop up your lips and give you a full look like what you have shown in your photos. However, we will need to determine if this protruding look is caused by only your teeth being protruding or whether there is a jaw component to it.
In most patients, this is caused by teeth being slanted out and braces alone will be able to correct this and improve your side profile. This may often involve extraction of teeth. However, if your bone is protruding, you may need to undergoing braces in combination with jaw surgery to get a complete correction.
I would highly recommend you to see an orthodontist so that we can take a side-view x-ray to assess your condition, explain to you the cause of the problem and discuss with you what are your possible treatment options.
