This is directly from the ADA"Currently, there are no reliable scientific studies to show that oil pulling reduces cavities, whitens teeth or improves oral health and well-being. Based on the lack of scientific evidence, the American Dental Association does not recommend oil pulling as a dental hygiene practice. The ADA continues to recommend that to maintain good dental health you brush twice a day for two minutes with fluoride toothpaste and floss between your teeth once a day and don’t use tobacco."
I've seen wider gaps corrected with bonding, so I would say that this is not too large to fix with bonding. Just realize that it will make those two front teeth look wider and you may want to consider braces in order to get a more esthetic appearance.
The implant looks like it is actually closer to the nasal cavity than the maxillary sinus.
There are many different levels of cleaning depending the health status of your gums and supporting bone. Periodontitis is a disease process where bacteria (found in plaque and calculus) cause damage to the gums and bone that support your teeth. We measure this by looking at the "Pocket Depths" around your teeth and by looking at the x-rays. A full periodontal chart should be done (recording the "pocket depths", which start at 1mm and go up to as high as 12-13mm). Normal ranges are 2-3mm (this would mean you probably need a prophy, or basic cleaning). Anything higher than that and you may have periodontal disease, in which case you need a "Deep Cleaning." Your dentist will let you know exactly what you need after he does a diagnosis. During the cleaning, there are many things to look for, like a plaque index (the purple stuff - disclosing solution), ultrasonic cleaning, oral hygiene instructions, hand scaling, flossing, etc. If you need a deep cleaning, you may also get anesthetic (numbing) in order to clean those deeper pockets. Hope that helps!
It looks like the space you have in the front is fairly large and would probably not be corrected with a single treatment. You may need orthodontics, veneers, and possibly even an implant to fix the space without making the other teeth look too large.
