Losing a bottom front tooth, how will a dentist fill this gap for me? Implant or partial?

According to my opinion, the dental implant is the best way to fill the gap between the tooth. With the dental implant treatment, the bones of teeth will be preserved and even, prevents the further damage of the facial structure. This in turn improves your appearance by restoring your lost tooth that looks and feels great like a natural teeth. 
Besides, the dental implants are built to last and are very cost-effective solution to get your lost teeth and thus, a beaming smile. It is crucial to seek advice from one of the dental experts to not mistaken while choosing the appropriate treatment and after care.

You don't say why you are losing your lower front tooth. So, if you have other missing teeth then your options are:1. Implant if enough bone.2. Cemented bridge if your adjoining teeth are strong enough.3. A removable bridge if you have other missing teeth. To replace only 1 missing tooth with a removable bridge is not all that successful.If finances are an issue, then you can bond the original tooth (if it is not decayed or broken) to the adjoining teeth. I have had this stay on for quite a few years on some patients. It is not a final fix to your problem but can work well until you are ready for one of the above options.All the best.

You could either have immediate implant placed in or wait and get a bridge. The cost should be almost the same.
