I have had a good look at the photograph. Yes you are correct.
These are indeed 'mamelons' which are completely normal and are of no clinical significance at all. Mamelons are actually 3 round protuberances which are a result of how a tooth germ cells forms enamel. Typically we see these at a very young age and after a few years of tooth wear either due to eating food or grinding the opposing tooth, these wear down rapidly.
In your case, I can see that your lower teeth are in front of your upper teeth when you are biting together. The reason why the mamelons of your front teeth are still there is because your lower teeth and upper teeth are not contacting each other.
You should consider seeing a dentist to discuss the possibility of orthodontic (braces). If you do decide not to have orthodontic treatment, then the easiest way to smoothen the edges is via enamel reshaping. This is a very simple and reasonably quick procedure which is done mostly without Local Anaesthesia and filing of the teeth in a very controlled fashion.
In cases where I do enamel reshaping, I will take a photograph of the teeth and confirm with you exactly what you wish to achieve. Some times I will take a mould and get a dental laboratory to give me a template to make the procedure easier. However in most instances, my patients ask me to give them the most desired result based on my aesthetic sense and experience.
