An additive solution with direct composite veneers is ultimately more conservative. With this treatment modality, composite resin is flowed around the tooth and protective volume is added. When performed well, the result is elimination of the dark space and often visual alignment of teeth. Smooth contours promoting improved hygiene and healthy tissue responses is our functional goal.</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img"

Patients seeking treatment have presented with gum inflammation from tartar build up, rough fillings, strangling over closure of spaces, or root wear and sensitivity from years of root scaling. Orthodontic correction of crowding can offer many benefits. However, adults should be aware that black triangles may occur or become more noticeable during alignment. In some cases, mild crowding and black triangles may be treated simultaneously without orthodontic treatment.</p><p></p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://www.discingqueen.com/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">This Substack is reader-supported.
