Protrusion 1.5cm should be abrupt. Is it wrong? Go to a regular stomatological hospital for examination. If you have high requirements for beauty, you can do it. Porcelain teeth are not extracted, but their teeth are ground slightly, and then a porcelain crown with dental materials is placed for bonding. If the teeth are too abrupt, root canal treatment may be needed (because too many molars will expose the root canal, you have to clean the pulp to ensure it. After that, the teeth will not be inflamed), and then smooth the teeth with a crown or post crown. There will be a month before and after. In short, beauty comes at a price. I'm afraid you don't understand. It's already said! There are also too many suggestions that don't know their specific situation.
